You seem to know a lot about recovering CSAM from the UTXO set. I'm not interested in doing that myself personally. I just want to know if it is technically possible to exclusively prune op_return data

I’m actually not aware of any script that does that, its not something that any sane bitcoiner would share. I only have done it with the whitepaper.
op_returns aren’t stored in the utxo set by design. So if you have a pruned node it won’t keep it around. but you might still have it in the utxoset somewhere else if there is some not stored in op_return.
an attacker likely would store them in the utxoset just to fuck with bitcoiners, not op_return
