I don't think the point was an "all lives matter" equivalent, but more "what's different about LGBT+ places that requires different training than any other club?"

If there's separate training, it's because there's something different about the process requiring a different curriculum. But it's not like gay clubs tend to be open spaces while straight clubs tend to have lots of rooms and hallways or something.

Regardless, the question's based on a misunderstanding. They're training employees of the venues at risk, they're not training police officers on LGBT+-specific tactics.
