Rod didn't become a shifter because he didn't devour or ingest the spinal fluid of a shifter. He just inappropriately ingested the Titan Serum and had a bad reaction to it by turning into an abnormal.

He clearly lost all sense of understanding like regular Titans. He can't make rational decisions, no matter what anyone tries. As for his status as a Reiss, the author probably didn't want to see the Coordinate going to waste on him like it is with Eren because he hasn't trained with it!
