It eventually gets settled when the corresponding Ligtning channel gets closed.

Where will the 100 sats settle? If I lost my LN address and generally when we create a LN address most UI I have seen don’t say this LN address is associated with this Bitcoin address and provide us with a private key for that bitcoin address. Not sure who gets those 100 sats.
That LN wallet of yours is using some lightning channel where your money exists.
If you use custodial wallet(i.e. Speed wallet or Wallet of Satoshi) and just delete your wallet, the wallet provider will get to keep custody of the sats.
