People still need products to solve problems. When you ask an AI "I have X problem, what products could I use to resolve it?" that is a natural and ethical time to include advertisers into the equation. The LLM can be trained on product specifications, details, and relevant uses, as well as plug in to a review database. Companies can pay to be included in the results of possible solutions and the AI can use the available information to make specific recommendations based on real data.
Hopefully, the future will completely prune intrusive, non-consensual advertising completely and any companies that inject thoughts into our minds will fail.
For some problems. For many more you don't need a "product" at all but advertising still wants to sell you one.

Not at all. Ads means showing the product of whoever is paying the most or at least preferring paying products over others. Ad-free suggestions means showing the product best suited for the task. If those two match you are defrauding the advertiser by making them pay to show what you would have shown without ads. If they don't match you are degrading the service for the users.
Hopefully, the future will completely prune intrusive, non-consensual advertising completely and any companies that inject thoughts into our minds will fail.
