If you are paralyzed, you aren't faster than Jirachi. That is the premise of paraflinch. Garchomp can't switch in on Jirachi without risking being paralyzed.
Body Slam is standard on paraflinching Jirachi. It was used on 32.648% of all Jirachi this past August, Jirachi's third most commonly known move; compare to Thunder Wave at 18.483%. It is hardly rare, and clearly the preferred method of inducing paralysis for the reason you stated: it paralyzes ground types.
I agree that Sand Veil poses a similar problem, and I suppose that Choice Scarf Golurk, Limber, and Inner Focus are the only counters to paraflinch. I must reiterate that both are uncompetitive in my view.
