If folks are going to use this for alt text or other accessibility purposes, maybe it's worth including in that text (or somewhere on the webpage) that the description is AI generated. Blind folks choosing to use AI tools on their own can do so with an awareness that the AI may sometimes make errors or hallucinate things, or leave out important elements. They can then try to account for those pitfalls when making decisions based on the text.
When someone reads alt text direct from a website, they naturally assume it was written by an actual person and expect it to be faithful to the image, without these kinds of issues. So while it's much better to have alt text than not to have it, it seems important that it not be unintentionally misleading.
