So I don't get the conflict here. Why would she ever object to getting drunk? Especially if it's to find the way out? Drinking alcohol is, like, her whole thing.
Basically what Naori has to do here is get Hinata drunk specifically to use her ogre powers to escape their situation, as opposed to just giving her food she needs to live. While I won't spoil how this plays out in the next chapter, Naori's main concern is that Hinata hates being an ogre, hence the whole search for the Kinpen Sudoku Sake, so the idea of forcing or even tricking Hinata to drink specifically to become an ogre isn't something Naori's keen on doing.
