I saw this cool article yesterday about edge aware pixelation. That might give better results when pixelizing AI generated pixel art.

More broadly I often find pixel art that has been upscaled and I'm wondering if anyone knows a good way to convert that back into the original?

In theory you just need to sample the middle of each blob, but I haven't found traditional image editors to be very helpful in this process.
