at least currently, for an something like this, you still need an illustrator.
like is it possible that the image is the raw output of an algorithm, selected at random by the person who does their twitter feed? yeah, i suppose so. but much much more likely is that an illustrator themselves generated a bunch of images, worked with other people to select a good one, cleaned it up, and then handed it over.
i’d bet there are probably studios producing internal concept art using ai, but also people sometimes use reference art from other games, movies, etc. for that purpose too. so i’m not sure it’s at the level of taking jobs… yet.
