You could also set up the lightning protocol to allow external funding. E.g:
* Perform initial setup with channel partner
* Setup transaction depends on an input that doesn't exist yet
* Once everything is ready, send a taproot address to someone who was about to pay me anyway
* that UTXO now becomes the input to the channel, and therefore it is open
Not an op-code expert so can't say for sure if it's possible, might require sighash noinput.
