I don't recall seeing anything in that particular bill as regards funding treatment, but I didn't do any broad research on what the General Assembly is doing on the mental health front. I just ran a search for "firearm" in the bills. If there is something else out there for funding better mental health treatment, it just didn't contain the word "firearm."
