Yes, in the same way a field of corn on a farm can be seen as art. We do not have full control over how it actually looks in the end, but it’s an expression by natural phenomena (sometimes guided or initiated by humans).
You could argue about the amount of free will required to create art. But in that case one could philosophically raise the question if humans even have free will, and if anything may be called art then at all.
I think if something is observed as art, it is by definition art. And perhaps everything that exists and is created could fit that description. But personally one of the more interesting types of art to me are where living beings are involved in the creation, while they’re actually thinking of creating art; and I think most discussions are about that concrete level.
Value of art is always in the eye of the beholder. If many people see the value, then it receives that from the public.
I would not say AI generated art has the same value as the Mona Lisa per se, quite the contrary. I’m only declaring both as a form of art.
