Would that need a web server and TLS cert?
It's a real shame most nodes don't support BOLT12 because it's literally made for this. Pure LN without the need for other layers and complications.
I have in my TODO list to implement lightning address with CLN backend on SatSale. Then it will work by just hosting lightweight Python process. https://github.com/SatSale/SatSale/issues/132

SatSale has built-in webserver, but for TLS you will need nginx proxy or something similar in front. For cert you can use certbot to get it from Let’s Encrypt.
Lightning address spec supports .onion identifiers too, then you don’t need all this, but not sure how good and widespread is wallet support for paying to such addresses via Tor.
What are LND doing?
