Probably a hardware device that syncs to an app on your iPhone using Bluetooth Low Energy. It could be health monitoring device such as a blood pressure cuff, blood sugar monitor, or even a car unlock app. It doesn’t need to be paired with the phone, only with the app that uses it, which is why you don’t see an option to remove it.
