What's the easiest dough for a Lemon Pie that still tastes good?
Well... Pie dough? Flour, fat, salt and water. I recommend lard for flavor and texture.

Alternately, a graham cracker crust can be had by putting the crackers into a plastic bag and rolling with a heavy rolling pin until fine crumbs. Then mix in butter, press into a pan, and bake until fragrant.
