A quote from the Apple Support article I posted above. It appears there isn't anything you can do.
"If you forget to sign out, you might not be able to use your device when your account is deleted."
If you are the original owner, contact Apple. Apple may be able to remove the ID if provided the required paperwork. Since the account is deleted, they may not be able to help.
Request additional support for unlocking your device
Either take the device, the original purchase receipt with the serial number, and a photo ID to the nearest Apple Store (if it has reopened). Call the store before going to make sure they can help.
