Only con is very little audience participation, but that's most games if you take out backseating.
More:
RE:4, SF6, Rocket League, Hitman.

I'm thinking Battlebit: Remastered wouldn't be her thing but she could manage to make it for a single stream just from the interactions of trying to command 126 nekofamis.
Other that don't fit nor would be popular but since she doesn't care at least something that would be interesting for her and the audience:
What remains of Edith Finch, Hotline Miami, INSIDE, tryharding Cuphead
