Can you run it as a keyboard instead of using lircd? I would then expect all the keys to work with that remote other than the info and menu buttons. That is how OSMC is currently configured to use that remote. We remapped those last two buttons with udev to get them working as well.
I think the hwdb file would look like this (with home switched over to a better mapping for Kodi)…
evdev:input:b0003v2252p1037*
KEYBOARD_KEY_7004a=esc
KEYBOARD_KEY_c0060=i
KEYBOARD_KEY_10084=c
