One thing that occurs to me, though, is that the sources for "highest number of tornadoes recorded per area" seem to have very population densities (Bangladesh is mentioned often, and the Netherlands and UK have the highest and third-highest densities of all the non-tiny European nations). This may be the reason that the reported numbers are so high for these countries: people are a lot more likely to see a tornado, even if it is too weak to cause significant damage, than in rural Tornado Alley. This is compounded by the fact that tornadoes are difficult to observe directly using radar, so tornado reports mostly come from people who have seen the tornado first-hand. And higher population densities lead to more frequent infrastructure that could suffer from noticeable damage, e.g. power lines, train tracks, etc.

Also I wonder if people being acclimatized to huge tornadoes in Tornado Alley leads to people reporting less of the smaller ones: a relatively benign tornado that would have somebody in the UK scrambling to phone the Met Office might just be ignored by their cousin over the pond.
