They have to disclose that Ai was used. So you should be able to filter them out. At least in theory. This should be a general setting in https://store.steampowered.com/account/preferences/ . Maybe you could exclude some titles by tags, but I would be careful to not exclude normal and good games by accident. Maybe there is a Steam Curator for this job (does anyone else use the Steam Curators?).
As for the Next Fest itself, my internet is extremely bad since 2 months. I have no clue what's on it right now... :-(
