I believe in this case, there's no actual battle or attempted Run Away happening. You're getting hit with a Curse that is forcing you to accept the bad stuff. The monster's normal effects don't matter. You can't just run away from the Curse, Steed or no.

Now in a regular battle situation, where you're losing to a monster in a fight and need to Run Away, your Steed wouldn't help you escape an inescapable monster. Your method of escape must tell you that it can let you escape even is escape is impossible. The Steeds (Raptor Steed in this case) don't say that, unfortunately.
