Apple sometimes takes out unneeded parts. This is the case here.
I’m away in VT so I don’t have access to the schematics so I can’t point you to what you need to check physically. What you need to probe the power rails to trace out the keyboard backlight power.
I suspect you likely have a damaged keyboard backlight unit or the cable connection.
Your memory slot issue is likely a warped logic board. Loosen the mount screws slightly to see if that corrects things.
