Nothing in the games suggest that any of the characters are LGBT, as Pokémon does not place any emphasis on character sexuality. However, it is common for LGBT people to dress and behave in manners similar to the opposite sex. With that said, one can imply that many of the characters in the game are "LGBT," such as Rika, Grusha, several trainer classes like the female Hikers and Guitarists, Ortega, and so on. Yet, this could simply be the result of the game attempting to do away with gender differences in terms of clothes rather than a true expression of sexuality.
