No. As far as we know, Death cannot create - at least, not the extent that God can, ex nihilo. And, if he were omnipotent, there would be no spell able to hold him, because omnipotent literally means he would have power over everything, but both Lucifer and Dean are able to bind Death (with varying degrees of success).
