Hi Brian,
Did a bit of digging this morning, hope this helps!
The GUI FLIRC is not terminal based in Linux and as such will show on the programs list in Ubuntu or Raspian. It won’t show up in Libre Elec. If you want to use the remote with Libre Elec the recommended way to do this is set up the remote using a Windows PC (this can also be done for the Linux installs as well) and then move the dongle over to the raspberry pi check out these guides, I found them quite helpful:
