"the quality, production, expression, or realm of things that conform to accepted aesthetic principles of beauty, show imagination and skill, and have more than ordinary meaning and importance." I think AI is capable of generating something that fits this definition. That's from Dictionary dot com. Merrian defines it as "skill acquired by experience, study, or observation". As far as I've seen, AI is great at aquiring skills. Now I think there are certainly levels to art (as someone who works in the industry), but I don't know why you wouldn't call it art just because it's generated.
