Sometimes, when I talk to random villagers, they'll start saying they've lost the key to their house or specific letters. Upon further inspection, the characters will also hint a location for such items; once, a villager told me they lost their keys near the river.
Is this an actual "interactive" thing between the player and the villager? Am I actually supposed to help them find these things? If so, how? I've found to information about this anywhere unfortunately.
Actually, you can catch the key without them mentioning the river. I've caught plenty of keys after only talking to the villager once, in which case they just say their key is lost. It is always in the river, never in the ocean. You must fish for it, and it will be a small, but not tiny, shadow. Think the size of a crucian carp or freshwater goby.
And the villager will eventually be able to get into their house if you never find their key. Sometimes I just don't have time to fish for a key or I forget to, and the villager can always get in their house the next day.

I have on occasion found a key while fishing before I've even talked to the villagers. This happens very rarely, and when I do, I just look for a villager who's wandering around outside of their home to see if they are the one who's locked out. If a villager is locked out, though, before I find a key, I talk to them until they mention the river. For some reason that makes it easier to find the key, don't know why, though.
