Full non-custodial Lightning is hard because it truly means running your own node which is an always on always connected server and managing channels.
The best halfway house is the Breez phone app which does manage to run a node on a phone and you hold the keys.
However I really don't recommend going down the Lightning rabbit hold of running your own node unless you really have some time to devote to it. Actually having a node which is useable requires a significant investment in time and BTC to have enough liquidity to do useful things with it.
Sup Brian, hope you're well!
