Can you test the USB-C port w/ multimeter on seemingly dead MacBook?
Is it possible to use a multimeter to determine if the USB-C port is dead before taking the laptop apart? If you open it up, how can you test to see if its the defective part before replacing it?

I appreciate all the responses but I think we're getting a bit off topic :) My original question was "Is there anyway to test the USB-C port w/ a multimeter to know if it's bad?" If I determine it's bad, clearly I'd order one to replace it.

So interesting discovery, when plugged into USB-C, the white battery light on the logic board comes on. I *think* this is a pretty good indication the USB-C port is ok but since it the laptop still doesn't power on, does that mean the logic board is bad even though the white light on the logic board illuminates?
Also, I don't hear a chime but it must be powering on to some extent because the trackpad is clicking which doesn't happen when the power is off. I can hold the button for 10s which would be the power shutting off and the trackpad doesn't click but then pushing the button to turn on (again no chime) but the trackpad does click.

What appears to be the problem with your port? Are you able to charge the systems battery?

Doesn't charge, computer appears to be completely dead.

So we don't know if the charger is working then. I would look at getting a USB-C power meter like this: Type-C Power Meter Tester for USB-C Devices

The adapter and cable are fine as I tested them on another MacBook and they worked perfectly. I appreciate the link to the meter though. Question for you… the meter won’t do me any good if it’s the logic board or the usb-c port right? Since the machine isn’t turning in, in theory it could be either and without turning on, it won’t draw power, correct?

Sadly I think you're at a crossroads. If you had a spare USB-C port cable you could try powering the system up via it MacBook 12" Retina (Early 2016-2017) USB-C Port Assembly .
But, I think its more likely the logic board got damaged from a static discharge or power surge, just like @jessabethany has pointed out.
