LLM based advertising has amazing potential when you consider that you can train them to try to persuade people to buy the advertised products and services.
That seems like a recipe for class action false advertising lawsuits. The AI is extremely likely to make materially false claims, and if this text is an advertisement, whoever placed it is legally liable for that.
I don't think we should expect that risk to dissuade these companies. They will plow ahead, fight for years in court, then slightly change the product if forced to ¯\_(ツ)_/¯
