Are you playing sun moon?You can't obtain it on the games. So, you need to obtain it in other way. If you have any other games such as XY or gold silver ,you can transfer a female Lickilicky from these game. Then teach it rollout and evolve. Breed it with a Pokemon from different languages game. If you finish the pokedex , get a shiny charm. And then, breed them. So the egg will have a increased chance of being shiny.
If you have a USUM game, you can SOS chain a lickylicky on poni gauntlet.
Hope I helped.
