[fleeper]

I don't have the option for changing the usb connection to ethernet. is it possible to still root phone without this option?

You need a USB-to-Ethernet adapter to connect the phone to an Ethernet connection.

As far as rooting, Stock Verizon G3 Update Rooted | Verizon LG G3 | XDA Forums for one source.
