So I was scanning through all these suggestions about editing code and creating new templates and blah blah. Everyone seems to have looked over 2 people’s suggestions which inevitably are the easiest and seems to be the correct solution.
I figured out that if I go into the pages from the dashboard, and hover each page it offers QuickEdit as one of the choices for a page. Select that and uncheck the Allow Comments checkbox. I think that may get the result you were looking for.

On WP 3.3.2 To remove the “Leave a Reply” open Pages = On the page you want to remove “leave a reply” click on “Quick Edit” and uncheck “Allow Comments” box
This works beautifully without editing anything.
