HomePods do not show up in the list of Bluetooth devices...at least they shouldn't. Try unplugging them and see if the two accessories remain connected to determine if they're actually the HomePods or something else.
The no disconnect / (i) button usually means it's part of an app. Do you have any Bluetooth devices you control with another app, such as LED lights, Bluetooth tracker, medical device, etc? Can also go into Settings -> Privacy & Security -> Bluetooth and turn off apps one by one to see which one(s) remove the two accessories.
