With a regular logo, the designer has copyright law to back them up. Pure AI creations so not seem to get that protection
Is not the selection and omission of poorly generated images the "human authorship" [1] necessary to qualify? Or can OP modify AI generated art meaningfully to qualify for copyright?

It reminds me of 3D art where there is a lot of up front work in making models, textures, armatures, and shaders. You send a ton of data to the GPU and it spits out a rendered image or more likely a tile of one. Sending a vector of bones does not seem much different then sending a vector of a prompt.
