Jimi Lightning on a Pi isn’t a good idea. You’re building on hardware that won’t be able to handle the size of the blockchain. I don’t pretend to be an expert, and I know you been in this space a long time. But I know of 4-5 pi’s that have died in the last month. Start9 doesn’t recommend using the Pi for anything Bitcoin related for this reason. Think about setting up on mini pc if you want to run long term. You can find used minis fairly cheap. Good luck.
