She came waltzing in about child support out of nowhere, this wouldn't matter to her father clearly. This was always going to end up requiring violence. Especially since I don't believe she's taken any time to actually understand the rules and laws of the world she's in. If she has, we haven't been shown any of it.
It's not like she has any noble figure backing her up of high position. From what we've already been hinted at, even an S rank adventurer barging into a noble's domain would put the S rank adventurer in hot water, so high standing adventurers don't seem to have a lot of political power, which of course begs to question the power structure in this fantasy world, but that's world building that would be required and it seems like the author is not wanting to delve into that anytime soon.
And any violence she's taking here should reasonably come back to bite her up the ass later. We haven't established that the butler somehow has a lot of political sway or dirt on his employer, and even then that has no guarantee of working out well for them, this is all a gamble and basically amounts to the same as just robbery/theft and fleeing the crime scene. Any of the servants who are favorable with her would just be marked as accomplices and strung up.
And it's not as if she displayed such overwhelming might that she dissuaded any repercussions that may come from these actions. She didn't even barter and provide the whole alcohol making venture as a compensation, which since it's happening in the household, it normally should be found out.
The fact that it's been so long and the father is completely clueless to the happening of his household is requiring him to be absolutely inept. Which he could be, but it was never shown. There's too much lack of information of her household here that basically any asspull excuse can be utilized, but none are provided, which is typically pretty bad writing in terms of creating a believable world.
But that aside, it's fairly clear that the intended goal here is to just focus extremely on the shenanigans of this overpowered child piloted by an adult child at heart who will go on a romp with an alcoholic uncle adventurer and just have misadventures with at most a base level world building to support whatever misadventures the author can think up.
