Well even though I haven't heard back I had some time so I decided to post up some options if it didn't end up transferring.
1.) Did some reading and I think I figured out how to use adb sideload. It's very similar to adb push. Only caveat is that you may need to update your sdk if you haven't already. If not, I'd just try it with your current configuration. Worst case, it doesn't work. But I'm THINKING since it's a function of clockworkmod, that it MAY show the transfer progress either by way of a status bar, maybe a % transferred, etc. If so, you'd at least know if it was working.
So since you already have the rom in platform-tools, you're all set since that's a requirement for adb sideload also. So then you select the adb sideload option in clockworkmod. Once that's done, open a command prompt, navigate to your platform-tools directory as before, and then run the adb devices command as usual. Then run this command:
adb sideload ATT-Stock-Rooted-D80010d.zip
2.) If you're still having problems pushing or sideloading a rom, it may be time to pull anchor and switch to the plan of reflashing stock. Remember in your previous state (couple days ago) you weren't able to turn your phone off without it auto rebooting into recovery. But since then, stuff happened which has allowed you to turn the phone off. So then, your chances of getting into "download mode" are very good if not almost a cinch. So you could then reconsider this whole deal:
LG G2 Stock Firmware (Go Back to Stock) - xda-developers
I think you're a green light for that now. Downfalls of that...you lose root so you'd have to redo that if you want rooted again. Also, you lose all the contents on your /sdcard. Not sure if that's a big deal or not but it'll be wiped. If it were a big deal, you could retrieve some or all /sdcard contents using adb beforehand.
Good luck.
