The striation city gym leaders Cilan Chili and Cress are DEFINITELY TOTALLY 100% based on the pokemon Simisage Simisear and Simipour evolution lines, since those pokemon are gen 5.
I remember, that the anime had pretty much the similar siblings with different eeveelutions, and each of them had a haircut, that represents their Eevee.
On the subject of your post, I think that each region has one. In Paldea, there are three trainers called the Dragon Sisters, each one using something related to dragon-types.
@Ridetherays Yes thats what Im thinking too! Especially since thats from Paldea and FROM THE GAMES which i LOVE (well except gen 1, those games are the worst)
