Hello, Jstark5, and welcome to the forum. Sorry for the circumstances that have brought you here, but I think that we'll be able to help you out.
My thought on this problem would be to get a clean container and drain the crankcase oil into that, hoping that the piece of foil would drain out. If not, leave the drain open and continue to pour the clean oil into the engine until it flushes the metal oil. At some point it should, and you can put the plug back in and use that clean oil to fill 'er up and be in good shape.
I'll move your post to another location where some others may have a better thought on your situation so you can compare ideas.
Good Luck, and hope to see you around the forum on a regular basis.
