no. all lightning payments use TLV onions i point this out to monero fans all the time and they don't get it when lightning payments fail, it's usually because one of the hops in the chain (typically 5-7) is congested or offline... the receivers generate the receipts and they are a set of hidden instructions layered in multiple layers of encryption for how to forward the payment adding the ability to do this with messages is just a matter of adding the mesage to the first layer (last to be decrypted, by the recipient) i'm glad i taught someone something today you can learn this in more detail by reading about how lightning network protocol works. Notably, look into lightning network messages and the sphinx protocol, which is the basis of lightning network payment routing
