In passkeys the bluetooth is used for the actual authentication protocol...

Sometimes, sort of. Most passkey usage doesn’t involve bluetooth. When it does, there’s no real data being sent over bluetooth, just a meaningless hash that can be confirmed using a secret inside the QR code.

So really, it’s like I said, Bluetooth is used to make sure that the device consuming the QR code is actually near the device that’s displaying the QR code.
