uBlockOrigin-HUGE-AI-Blocklist: "A huge blocklist of sites that contain AI generated content for uBlock Origin & uBlacklist"

See my comment about using it with uBlacklist, which does exactly that. By default it is configured only for google search but you can enable other search engines in the options.

Read the linked github page. It's got a full guide per platform.

There’s instructions and an instruction video in the link for adding to uBlock Origin Firefox extension. Also says uBlacklist (Firefox and chrome extensions), PiHole(raspberry pi set up to filter traffic on your network), or AdGuard(browser extension and app).

You can probably implement with a router blacklist if your router supports that but that’s beyond my knowledge
