i should point out that, at this point, i don't think any LN implementation leverages taproot, as it only just got to a point where you can usually get TR transactions into a block in the last year, maybe it started to become possible last year, 2023

LN needed no malleability, and that was the compromise that we ended up with, that's all there is to it... and for whatever reason, this isn't the centre of why we now have fairly majority support for taproot, even though schnorr signatures have been on the radar since 2016
