Regardless the scale, big or small, if you produce and spread untrue information to defame others, you are liable, period. These AI content are purely generated by Google's half baked AI. Not any other third party. So Google is 100% liable here.

If you just display third party content, that's one thing, but if you generate content yourself and those content are false, harmful, that's on you. Google should be shamed to do this kind things recklessly and irresponsibly.

First they had links to other sites. Then they put the information found on other sites on their own site. Then they took the information from other sites, trained a LLM with it, and put it on their own site without even linking to the source.
