Decided to make a new thread myself for this so I can get the responses via email. Here you can report any minor errors with the main site instead of starting a lot of new questions. Things you can report here include:
As I fix the errors, the answers will be hidden. Try and keep comments to a minimum to avoid clogging up the page, stick to important things like additions/corrections to the corrections.
Remember, small corrections only! If you're reporting something more substantial than a missing picture or incorrect data, please make a new thread!
The Low Kick and Grass Knot pages are missing Gen 8 mons (as well as Melmetal) that weigh 200 or more kg, the Pokemon that weight this much are Zamazenta (Both forms), Zacian (Crowned form), Dracovish, Stonjourner, Copperajah, Melmetal, Gastrier, Calyrex (Ice Rider) and Eternatus. It's also missing Kommo-o totem form and Araquanid's totem form, but I have no idea if those count too.
Swarm has no effect on the wild Pokemon encounter chance. source
Rotom’s page, on the type effectiveness chart, says Ground doesn’t affect Rotom. While this is true, since abilities aren’t in Legends Arceus, ground types now can hit Rotom.
When using the old type chart option for the "Pokémon attack type coverage tool" it doesn't change any Pokémon's types back to what they where prior to gen 6, just removing the fairy type from them, making most of those Pokémon have incorrect type match-ups. As well, I don't see any reason why it will still check against gen 6+ Pokémon when this mode is only applicable to Pokémon found in gens 2-5.
In all of Basculin's locations in Legends: Arceus, it says that it's a Red-Striped Basculin. I'm pretty sure that all of the Basculins in Legends: Arceus are White-Striped. Also, Tranquility Cove is missing Starly and Staravia, and Heart's Crag is missing Rufflet. There is also a missing location call Crevasse Passage which as far as I can tell has at least Bergmites.
Rhyhorn's Yello level 1 moves are incorrect. Source: https://github.com/pret/pokeyellow/blob/master/data/pokemon/base_stats/rhyhorn.asm
On the Reckless page, the text below Moves Affected is read as the following, despite none of the moves on the list being punching moves:
The attacks classed as punching moves are shown below with their normal and boosted power:
Additionally, the text below Effect lists High Jump Kick and Jump Kick as being unaffected by Reckless due to having fixed recoil damage, but I'm pretty sure they're not the only two, as I'm pretty sure Steel Beam and Mind Blow are unaffected by Reckless too.
Reckless increases the power of recoil moves by 20%. By extension this means the amount of recoil damage taken will increase as more more damage is dealt (except for High Jump Kick and Jump Kick which have fixed recoil).
Aside from the Game Descriptions, the Gale Wing's page doesn't mention that from Gen 7 onwards, Gale Wing's only works if the Pokemon is at full HP.
I found a location of SudoWoodo that is not listed on the site. In Emerald, you can obtain one from the Battle Frontier. I am not aware if there is a reason for not listing this, such as the static exchange of Pokemon not being a "Location" per se.
If so, please let me know. Otherwise, I am going through up to White/Black 2 with a "Live Pokedex", and will keep an eye out for any other discrepancies.
Thank you for this site! It has been extremely helpful in my search, far and wide!
On the Corsola page, it says that it is not obtainable in HGSS, but it is. Not sure if there are any more errors on this page, but that's what I found.
Some moves are inaccurate on some Pokemon's Legends: Arceus move pages Overheat says it does 130 damage but it does 110 Leech Life says 80 but it does 75 Ice Ball says 30 but it does 40 Rollout says 30 but it does 40 Aqua Tail says 90 but it does 85 Earth Power says 90 but it does 80 Flamethrower says 90 but it does 80 Outrage says 120 but it does 90
Fury cutter was introduced in Gen 2, but it says that in Gens 1-4 it has 10 BP
For Lance’s Team in the HG/SS Gym leader and E4 Page, the level for Lance’s Gyarados is wrong. Instead of level 44, it should be level 46. Source (if I need one): I was watching my friend fight Lance
Cotton Down's effect is listed incorrectly. It lowers the speed of all other Pokemon, not just the attacker. This is what Bulbapedia says:
When a Pokémon with this Ability is hit by a damaging move, the Speed of all other Pokémon is decreased by one stage.

It's says you have to trade/migrate from another game to obtain regigigas in sword and shield but you only need to trade regidrago/Regilieki to get it.
The effect description of the ability Steam Engine seems to be wrong when compared to the information on other pokemon websites and the actual in-game effect.
Pokemon Database:
Steam Engine raises the user's Speed by three stages when it is hit by a Fire- or Water-type attack.
However, it should be:
Steam Engine raises the user's Speed by six stages when it is hit by a Fire- or Water-type attack.
Suicune is slightly different in that it doesn't exactly roam, but when you walk nearby, it flees to another location. After a few times you will be able to battle it. See the PokéBase question, Where is Suicune? for the locations.
The 'Where is Suicune' links to this page, which is hidden.
In all generations after Gen 5, Dialga does not have Shock Wave under Transfer-Only moves, whilst still not learning it any way in those generations.

On Nanu's section, the sprite is for Persian instead of Alolan Persian. Same thing with Kiawe, which has Marowak instead of it's Alolan form.
These errors are also present for their USUM sections.
Edit: Hau's page shows Raichu. It's supposed to be Alolan Raichu.
On the Thunder Stone page, it doesn't mention that Tadbulb evolves into Bellibolt with the Thunder Stone, nor does it have the description for the Thunder Stone in Scarlet and Violet, which is: A peculiar stone that can make certain species of Pokemon evolve. It has a distinct thunderbolt pattern. On the Water Stone's page, it doesn't have the description of the Water Stone for Scarlet and Violet which is: A peculiar stone that can make certain species of Pokemon evolve. It is the clear blue of a deep pool.
Type: Null in the language part says that is called like that in Spanish, his Spanish name is "Código Cero" which means "Code Zero"
