I don't Raiden is made aware of Moloch and Drahmin, plus he never even encountered them in the storyline of Deadly Alliance.

Even if he did knew them in the original timeline, he never fought them as the Oni fought Scorpion and won, disappearing into unknown as Shang Tsung's palace was destroyed thanks to Raiden's attempt of sacrificing himself to kill Onaga (which it didn't work).

I don't the Oni would be good allies to Raiden even if he tried interacting with them.
