they have three similar elements (stove, chair, and window)
First you oversimplified the similarities, and you then minimized its significance. Minimizing AFTER oversimplifying is essentially a straw man argument.
The window in Rockwell's piece, for instance, is small and rectangular while the one in Bazille's is huge and arched.
They are both structurally rectangular and similarly proportioned (height vs width).
The chair in the Rockwell piece is actually barely identifiable as a chair at first glance, whereas the one in the Bazille piece is immediately recognizable as a wooden chair.
They are the same thing in terms of scene composition.
They're also three objects that are likely to be close to one another.
But they are not merely close to one another they are arranged in a particular way creating similar scene composition.
Plus, you missed entirely the angular element on the left side. The staircase in one, vs the bookcase in the other, again both serving the same compositional task.
For instance, my aunt heats with wood and has a stove roughly the same distance from a window as in the Rockwell and Bazille pictures
And if you happen to have a photo that not only illustrates the 3 objects in roughly the same positions, with an angular element on the left side, but also that the photo was taken from such an vantage point so as to frame them compositionally in a similar scene... then you might have something.
Lets stipulate that your aunt actually lives in a room just like that. Even then, you might well have hundreds of photos of your aunts home, and not a single one of them have the same composition as these paintings.
I think all this proves is that people tend to put their stoves in rooms with windows and chairs.
And then take a photo from a vantage pont with an angular element on the left, a single chair in the foreground, with a group of people in the background, but not the focal point, catching the wood stove on the right?
How many of them paint this particular scene composition?
Frankly, these paintings ARE remarkably similar -- that one influenced the other is not a foregone conclusion, it could be coincidence, but it certainly merits consideration, even investigation.
