Randolph, I looked at both the crankcase cover and crankcase. I have the lower cowling on my '14 DL1000A and wasnt in the mood or to pull it off for inspection of the area you pointed out, but...
Is it possible that there is no plug, that it is a vent hole of some type, and what is leaking is the left crankshaft seal behind the alternator rotor and/or the cover gasket itself?
The factory service manual calls for draining the engine oil for generator removal, but that me be required for clutch slave cylinder removal.
I'd spray that area down with Brake Cleaner, put 20-40 miles on it and recheck for the source of the leak.
No plug shown in the parts microfiche or service manual.
