What protocol are the Android phones using to connect to the laptop? It's been about 6 years since I've had an Android and I can tell you that my top-of-the-line Samsung needed to have WiFi enabled to be used as a personal hotspot.
and why would they need to constantly be looking for a wifi or bluetooth device/signal to connect to to be able to act as a router?
If you are using your iPhone as a personal hotspot, it can work in one of two ways (assuming no wires). In both cases, it connects to the internet via cellular data. Then, it shares that connection with other devices either over WiFi or over BT. It's essentially acting as a router. And just like a router attached to cable or fiber or DSL, it has to have WiFI turned on.
If you are using WiFi to connect to your laptop, you don't also have to have BT enabled, but I can't think of a reason to bother turning it off. It uses negligible power if it's not connected. I haven't checked to see if you can turn off WiFi if you're tethering using BT. I will leave that as an exercise for you.
