70D why doesn't the af assist beam fire in live view?

I haven't found anything specific that says that but it seems to be the case. Maybe there is a mode to manually select while in live view that will allow it?

I know it's really annoying, but sometimes in low light situations what else can you do? Maybe manual focus.

I've tried all the Silent LV shoot options and none of them enable the assist. Also tried with and without the flash popped up. This is in P mode.

The 70D will not AF assist in the LV PDAF mode except with the 320EX flash.  The 70D will use the LED on the 320EX for focus assist.

That's good to know. Does it use the LED for focus assist using the optical viewfinder too? I don't know why Canon didn't design the 320EX to use the LED as a focus assist light from day one.

It will use the LED in LV with both the CD focus and the new twin-pixel focus but never in any form of the Quick focus LV or VF  The 70D will also turn on the LED in video if needed and turn it off when not needed and I did not see a control for that other then the auto/man led switch on the flash.
