I am using an LLM in an app. Got this in the Appstore review: Your app includes AI-generated content but does not appear to include content filtering at this time. Since your app may produce content not appropriate for all audiences, it would be appropriate to revise your app's age rating to 17+ in App Store Connect or implement content filtering. There are two ways to resolve this issue: You may update your Age Ratings selections to 17+ in App Store Connect. Or you may implement content filtering so that all generated content is appropriate for your app's current age rating. I want to get the age rating lower than 17. I can see lots of posts about how to do this for user-generated content. But how do I implement AI-generated content filtering?
