Re-center/align mouthpoint
The mouthpoint is a great tool for various creative uses, but it's really tricky to switch between 0 influence and any influence without creating some sort of whiplash motion of the head (especially if looktarget is involved), which isn't ideal.
One possible way to mitigate this would be to have a button in the mouthpoint object to set the position of it directly where the current actors mouth is, so any influence on that frame has minimal impact on movement, which then allows us to animate the mouthpoint without that initial snapping.

Right now you can work around this by having the mouth point active in every step but setting the influence to 0. When it's needed, just increase the influence and it will more organically make the transition. This same technique helps avoid jerkiness with random movement nodes.
I'd be a big fan of the button you describe in the 2nd paragraph though.

Unfortunately this doesn't work in tandem with looktarget, since any influence of mouthpoint overwrites all positioning gained from looktarget, meaning that the initial head positioning will be based on where the head would be with looktarget not in use.

I think I understand what you're getting at now. I usually keep the influence fairly low while using looktarget and adjust the mouth point position so there's no big jumps.
