I've been thinking maybe this has nothing to do with pi the number and more to do with pie the dish.
So probably I'm wrong, but when googled for source/origin of pie I got result as Romans/Greeks/Greece? If the answer is Greeks the answer also coincides with the origin/root of the letter pi as a Greek letter and the country is also named Greece (6).
