Just because you're not the target audience doesn't mean there's not a real target audience.

There a people today learning to use an LLM instead of an actual search engine. For these types of people whatever happens outside of the LLM app is invisible to them. The social media apps did similar where they started letting people purchase directly within the app. People started looking at these shops rather than doing searches for it elsewhere.

Buying things on a social media app is crazy to me, but I don't use the social media apps. Buying things from an LLM app seems crazy to you, (because it's new and it's borked is fixable), but to people that first turn to their LLM app of choice that decision isn't so crazy.

Social media apps generally opened up new markets though of their existing user bases as sellers. Perhaps chatgpt could know everything in your house, if you don't actually use it, and pair you with a neighbor that needs it!
