Well it doesn't in Red, Blue, Yellow, Gold, Silver or Crystal, it just brings up the message "No! There's no running from a trainer battle!" and lets you select something else.
It also doesn't in Ruby, Sapphire or Emerald, it just brings up the message "No! There's no running from a TRAINER battle!" and lets you select something else.
It doesn't in Platinum, Heart Gold, Soul Silver, Black, White, Black 2, White 2, X or Y either, it just brings up the message "No! There's no running from a Trainer battle!" and lets you select something else.
So unless it does it in Fire Red, Leaf Green, Diamond or Pearl, it doesn't do it at all. By the way I'm unable to test these out due to not having the actually games, so if someone wants to test them out to add to this answer feel free.

I also tested this theory out in some of the games I tested above and the results were the same.
