My grandma told me that she saw a movie at around age 6 in which a big dinosaur rampaged through a city and picked up skyscrapers in its hand. For years she was afraid of โ€œdinosawersโ€.

This would have been around 1933 or 1934 so NOT Godzilla which was my 1st guess.

Any ideas what film it was?

According to this article, there was a The Lost World version on 1925 with a dinosaur terrorizing a city; but it was a brontosaur, so no hands. Maybe she made up the picking skyscrapers in its hand bit? Time is a bitch, and kid's imagination tends to run wild.
