I guess there is no harm in asking either company, worst that would happen is they’ll say “not us”.
Was the battery still working when you found the device?
Google offers a way to use Android phones to hunt for some types of trackers.

Apple has similar for iOS/iPhones.
Being a bit paranoid here, but if I wanted to spy on someone, I would plant TWO trackers, one to be easily found such that the person would think “hey I found it”, and the second one more hidden.
So do NOT tear the car apart—but you might want to use one of the tracker detection methods mentioned above.
