I can't tell if this is sarcasm or not but AI is next to useless in 3D graphics. Some studios are experimenting with using it for iterating on concept art. I can even believe it if some studios are using it for some background low priority textures.

But for actual production models, AI models do not produce usable model right now. Their topology is so bad that they could not be animated. Even if you just need a static model, the topology is so bad that it would not support making minor fixes to the model.
