I don't really get why people find Kaoru's actions confusing, it's pretty straight forward and an obvious pattern.
Town 1: tried to help people while securing food and shelter, backfired due to not knowing the details of the world and making too much noise.
Town 2: tried to help people while securing food and shelter, backfired due to being too smart and still having no protection from meddling by the nobles.
Town 3: kept her identity hidden to prevent a repeat until she could do something flashy enough to be untouchable.
What she's done is a mutually assured destruction style approach... enough people know who she is that...
* if one group tried to monopolise her openly the others would intervene for fear of divine punishment,
* if someone tried a repeat of the abduction approach she'd simply blast her way out and go "what did you expect to happen?"
* if someone tried the proposal route she now has some shielding thanks to friendly nobles
* if she says she's planning to leave, people will try really hard to deal with the reason for leaving, on account of the amount of people she's healed.
By this point in the story she fully understands how to abuse the power she has (to the point she can and has used it to insta-kill people not too far in the future from this arc), so she's not particularly concerned about being imprisoned or abducted.
She's also not the kind of person to just sit there and do nothing when people are suffering, even when it causes her trouble later. It's not like she has family in that world, so she can disappear to another city or country whenever she wants.
Hell, the first conversation with Celes tells you she's going to be a meddler when she explicitly asked if there would be any problems with her making improvements to the world's standard of living and encouraging Celes to do the same.
As for the translation quality... if you think this is bad I can point you to some much, MUCH worse translations. There's one in particular where they can't even keep pronouns and names consistent for an entire line, let alone a paragraph.
Loli o Mamoritai is pretty open about not being a native English or Japanese speaker and usually listens to feedback... complaining the quality isn't good enough is pretty entitled considering it's being done for free. But hey, I'm sure the people saying to get a native English speaking editor have all submitted an application for doing that job themselves, right? You're not asking more people to do unpaid work for the sake of your entertainment, right?
There's a saying I quite like: If you think you can do better, you're welcome to do so.
