I was just informed of a new platform to publish through, and some will have heard of it. Ream.
Their guidelines are here.

I’m also going to create more illustrated style covers using the image rendering program I have because I find they are the most versatile. (It’s what 3d rendered image creators were all doing before AI came on the scene. ) But, because of AI infiltrating the image stock/design market and the court case around those (midjourney) I am still steering clear of anything AI
Anything that is illustrated on my site has been created through a rendering program that has a license or is CC0. Basically, It is Not AI derived.
I don’t know if AI designs on covers will some day mean those covers are pulled, but I know I personally don’t want that hassle.
