As ridiculous as it sounds, have you considered adding report functionality to the other (non-UGC) content in the app? It seems like the review team isn't budging with your current argument so it may be worthwhile to add report functionality (even if the actual reporting is basically a no-op) just to appease them.

Heck, even feature flag it and disable it once the app gets in. Probably won't be flagged again in subsequent reviews.
