If I remove a device from my account through Apple ID account management, will it essentially just sign that device out of the Apple ID and I can sign it back in again? I am trying to sign out of the Apple ID on the device itself but it is stuck loading and I can't even restart the device.
If you remove the device through account management, the device should be able to sign back in.
Try a forced restart.
If necessary
Do a backup and try a factory reset. Then restore from your backup.
Backup - Restore your device from an iCloud or iTunes backup.
