Yeah it’s basically just a Trolley Problem scenario. Two people were laying on the trolley’s current track and would have been killed if she refused to pull the lever. She pulled the lever, diverted the trolley, and killed one person laying on the second track to save the two laying on the primary track.
Sure, the philosophy people could argue that she was murdering the one by acting. But if she has the opportunity to act and refuses to do so, many more would argue that she was complicit in murdering the two. She made a choice and knew she’d have to live with it.
Neither side is more “right” than the other. That’s kind of the whole point of the trolley problem.
