It could be that some of the bolt holes on that case go into the oil, but there is plenty of material around that bolt hole, you didn`t weaken the case by drilling into it.
Hylomar will seal those threads no problem, we use it to seal threads on jet engine bearing compartments...

When I get home today, I'll see if there is any significant leakage.

Well, I got home from work, and it hadn't dripped onto the lift yet. But there was a bit more seepage than I was comfortable with seeing. So I drained the oil from the transmission (needed to do that anyway), pulled out the fastener, and cleaned up inside the hole/threads as much as I could. I put a small pin punch into the hole to see how far it would go, and it went in far enough to convince me that the threads went all the way into the case.
So I took the Hylomar suggestion, cleaned all the liquid teflon sealant off the fastener, gooped it up with a thick coat of it, and put it back in. Torqued it to 15 lb/ft and I'll let the Hylomar set up for a day or two before I put any oil in. If it seeps oil, I'll just have to live with it until I need to pull apart the transmission.
About all I can do right now.

I'm hoping it does too. If I'd have known the thread went all the way into the case, I might have put the drill a bit further, thus getting the helicoil in a bit deeper. I thing I've got a good 1/4" of helicoil into the case. It holds torque great. just can't get it to stop seeping oil. Going to be riding season soon, and I've still got a few more things to do on the bike before then....

Congrats on the 5K!!!!
I considered just gooping some RTV into the hole and seeing what happens. I think that is what the 'mechanic' did after he realized he'd stripped the threads. I can deal with a bit of a seep. I can't deal with a steady drip.

RVT should work to. The Gasket maker sealer will also act like Loctite and you wont have to tighten dn too much.
