Such a weird thing. .aigc isn’t a real toplevel domain, and when I searched for it I found that apparently TikTok uses it as an abbreviation for “ai generated content”. That fits with the fake headlines. I was going to suggest checking /etc/hosts to see if some lines had been put in there by malware to make fake domain names capable of resolving, but you say the links don’t work. So that’s weird.
So is this just something wrong with Google?
