I agree with you. Aside from some archery, she has no combat capabilities whatsoever, and currently lacks the 2 most important things to use her archery. I get people want a self-supporting FMC, but come on people. This isn't the kind of story where FMC is some badass combat expert. She is primarily a maid, hence the literal title.
I do find it odd that some people think she could handle them already and that showing gratitude to the prince for saving her is somehow wrong (which also, she does not seem to recognize it is him, or at least does not acknowledge she knows it is him). For 1, what prior to this event has shown her able to save herself from 3 (possibly more) men while being held at knife point and while also wearing heels on a cobblestone road? The answer is that there is not a single event.
2, it is very normal to repay kindness, especially when it is to someone who essentially saved your life. She likely, if left unsaved, would have been either raped, sold as a slave, sold as a sex toy in some underground auction to some perverted merchant, brothel, or noble, tortured, abused (possibly permanently disfigured, scarred, burned, etc...), or any combination of them. All of which end in an early, painful death. So yeah, she is gonna be thankful for his help. She even asked for it. And for those who are saying she is dumb for just going along with him. She knows he does not mean her any worse harm (since he went to the trouble of saving her, even staying around to turn in the criminals), and that he has some level of authority or prestige, since the knights treat him differently than other commoners. So staying with him is almost a guaranteed safe choice. Actually, if anything, it could be worse if she refused. While nothing likely would happen since it is the Prince and all, she does not know this. It could be taken as an insult. It would be essentially her saying "It is only natural to save me, why should I repay you for just doing what is already expected of you?".
