I'm not convinced this is any worse than searching for results or reviews and being directed to content that is affiliate supported (or astroturfed by companies). Humans already do this sort of subtle nudging and lots of people position themselves as unbiased. So many blogs are annoying "buried lede" advertising where the article seems vaguely useful until you realise that it's just a veiled attempt to sell you something. Virtually every reviewer on YouTube seems obliged to open with "my thoughts are my own, the company doesn't get to edit my review, etc."
On the other hand, a good LLM would be able to suggest things that you might actually want, using genuine personal preferences. Whether you think that's an invasion of privacy is debatable, because it's perfectly possible for an LLM to provide product results without sharing your profile with anyone else.
