You want the ESP32 to use the phone as an access point over Bluetooth? This can’t be done with the default Bluetooth stack but https://github.com/bluekitchen/btstack is a Bluetooth stack for various platforms and has PAN support. This isn’t to say that it is easy though, I don’t think it has direct support for Arduino, you’ll have to use the ESP32 SDK directly. So this can be done but the learning curve might be to steep considering your experience.
