Ah, I didn't know that qi pills got nixed from combat actions. Sorry about that.
Two actions of setup against something that doesn't seem like it can intentionally activate its dispel looks like a pretty good deal. Additionally, there was only one mention of that dispel explosion, and I think LQ got her mist back up after that. It's described as "aimless in its rampage", and it's mostly focused on LQ, so there doesn't seem to be as much of a risk towards her subordinates if we decide to fight it. Especially since they're staying away and setting up barricades.
Zhengui can run interference for the scouts, heal when need-be, while Hanyi and LQ can start to chew away at this thing's health.
