As far as I'm aware countries fall broadly into two camps. Camp 1, USA for example, is concerned purely with the abuse of children, i.e., anything that depicts or is constructed of pieces of real children is illegal but other things such as drawings, stories, adults role playing, etc is not. Camp 2 outlaws any representation of it whether or not a child was involved.

Nowhere will a training set featuring pictures of naked children be legal.

Appropriately from the recent news stories, but it's easy to imagine at least portions of such pictures being available for medical diagnostic purposes. I've sent pictures of my children to my doctor, so presumably in the future it's easy to imagine sending pictures to an AI to diagnose which would require a suitably fleshed out (pardon the pun) training set.

I imagine the AI which diagnoses your children won't be the same AI your neighbours use to make pictures with.

True, but generalizing beyond the training set is precisely the point of machine learning. A good generative model will be able to produce such images, no matter how heinous the content is.

Actually ... we just did a good job of making generated child pornography ubiquitous.
