Amara was introduced as having existed before anything else, but Death is not the concept of death; merely a representation of it. He wasn't around when she came into being, but that doesn't mean the concept wasn't already there. We don't know when Death came into being relatively to death.

Chuck's suicide plan wasn't a suicide plan. He was going to be caged, remember? At least that was the deal he was going to make with Amara. If she went back on their deal, that's when the Winchesters would have to do something about Amara (probably free God or something like that).
