When search results are just links to content related to a topic, the provider isn’t responsible for the accuracy of the content, which is created by others. But they are responsible for their own summaries and other provider-created content.
This is clearly a reasonable line to draw. This is not content created by others. It's your robot. Fix your shit.
Saying "I slapped a disclaimer on my libelous robot that says that it may generate libel" doesn't grant you the right to be libelous.
