Not really. Damages can be put down to the massive population increase (close to tripled in the US) since the 1950s and urban flight toward suburbs that sprawl miles around cities, which means more people have homes and thus more likelihood of tornadoes hitting and damaging property owned by humans instead of what was previously a field or a forest.
Not to mention tornado damages have DECREASED:

But again, it doesn't actually show frequency over years, it shows frequency of those detected. Which has changed with the much better technology we have enabling detection of many tornadoes that would never have been detected in the 1950s.
