While it does seem like the insurance company is most likely "at fault" for the fraudulent data, how did none of the researchers catch this?

My understanding is that even looking at a histogram of the mileages should have raised serious doubts about the data.

That's so, so easy to happen, specially 10 years ago. If they're not already primed to think a dataset might be fraudulent, a researcher might likely just think they've won the statistical signal lottery.
