Thank you for your suggestions. I checked and tried all of them, but still can't get it to work. I'm 99% sure this is a bug. It happened exactly when the version Android was updated on my phone. I think it's a specific issue with the way I selected Charge Only, the LG-specific options, and the Android update.

Have I tried a different computer? Yes. I have tried it on Linux, Windows 7, and Mac OS. The Linux computer is the computer I was previously able to use to connect to.
The pop-up option does not return, even though I reset the phone to factory settings. It is locked into Charge Only mode even after a full settings reset.
I don't remember if I've tried flipping the USB-c connector over in the phone, but I've tried several dozen times, so I'm sure I've randomly had it both ways over the course of my experimentation. Also, I would expect the super expensive ones I've purchased would work both ways. I've also tried jostling them in the port a bit to no effect.

If by STORAGE you mean the option I see in the General tab of my Settings, when I click on it, it only has device storage options and there are not three dots anywhere. I've explored every inch of my settings looking for places to affect the USB connection type. It's not an issue of me just not searching hard enough for the option.
