OAI-AdsBot
OAI-AdsBot is the tool or developer fetch run by OpenAI: OpenAI ChatGPT ads page validation. Its operator publishes the IP ranges it crawls from (https://openai.com/adsbot.json), so a request carrying the name can be checked against that list.

User-agent: OAI-AdsBot Allow: /
Add a group that names it: "User-agent: OAI-AdsBot" followed by "Disallow: /". A crawler follows only the most specific group that names it, so once a group names OAI-AdsBot, rules under "User-agent: *" no longer apply to it; repeat in that group any Disallow lines you still want.
What blocking it changes
No. It is a third-party tool's crawler. Blocking it changes what that tool knows about your site, not anyone's AI answers.
