LGBTQ+ representation in the Pokemon anime

That's really complicated to answer. I'd say yes, but we're talking about a Japanese franchise. Few people here are familiar with such different culture, and I think only them'd be able to give a full verdict to that.

As far as my knowledge goes, I think those sort of things tend to be avoided in Japanese children shows (unless it's a side character of course). Course I'm not 100% sure of what I'm saying here, but that's the impression I have.
