....should I add a ground wire that leads back to the service panel?

In my hometown, 2 wire and conduit is "to code", but would a ground
wire make the ground more "robust?"

Also, I talked to the electrical inspector and he informed me that 2-
wire and using conduit for ground is a "dirty ground".

If I'm understanding you correctly, you want to run new circuits to a
room. Pretty much all cable sold today in HD or Lowes, whether BX or
Romex already has a ground in it anyway.
