There is somewhat famous digital artist from Russia - Alexey Andreev. Google it, he has very distinctive style of realistic technique and surrealistic situations, like landing big manta ray on the deck of aircraft carrier. Or you can see his old works in his 5-years-not-updates LJ [1].
Now he uses generative AI as one of his tools. As Photoshop, as different (unrealistic!) brushes in Photoshop, as other digital tools. His style is still 100% recognizable and his works don't become worse or more "generic". Is he still artist? I think so.
Your definition assumes that photography is not art and/or doesn't involve conscious skill and creative imagination. That's not the consensus, to put it mildly.
