Mmm … my understanding is that a sender can prove a payment was delivered by supplying the pre-image. That said, a relay would have to prove that the pre-image and payment_hash was indeed relevant for that tip. That may be resolved with HODL invoices.
Bolt12 includes payer proofs. If we ever see wide bolt12 support, youd be able to have a “receipt” for the ln payment.

No payer proof can stop him from reseling the note
