I totally agree here, that 'culture fit' in team work is a real thing. Usually a thing that you discover some month later, after the person feels they can be "themselves" and don't need to pretend being nice. If the whole team finds a person toxic, this is very real case of 'culture unfit' and it should be dealt with.

However, I also once faced with a case, when manager didn't want to hire an engineer, because she thought he wasn't 'culture fit', although he was a great engineer. Technical members of hiring committee managed to convince her otherwise and then this person became in a sense the heart of the team, everybody liking him more than anybody else.

So, in my opinion 'culture fit' should always come from within the team a person works in and it should be a collective opinion, not an opinion of a single manager.
