+1. she is gone.
You can find her body, but it's kinda buried.
Wait, how??? Pushing her out in Avernus and the body ends up somewhere on the sword coast? One reason to keep her a bit longer would be that nice plate she wears.
If she dies on the ship, you can loot her body on the beach. Not sure if you push her out of it though. I guess you can't.
As for the OP request, just let her die in your next encounter and don't resurrect her.
