Afaik a lot of AI generated models aren't really 'AI generated' in the sense that you have an network that outputs vertices and topologies and UV maps.
3D AI models are usually made by a grab bag of techniques, for example you use diffusion to output color and depth maps from multiple angles, then you try to put the results into a voxel grid with 3D reconstruction techniques, after which you run an algorithm like Marching Cubes to get a crappy mesh, and then you do decimate the mesh via some algorithm.
So yeah, the outputted model is built out nothing like a 3D artist would have, might look okay, but you won't find any structure in the output.
I don't think it's worth using them as anything in an artist pipleline except maybe as reference for retopo.
