The rate that the tank valves are opened won't affect air in the lines, but too quickly can trip the excess flow valve in a tank hose (pigtail), requiring the valve to be closed to reset.
Tank valves don't really need to be opened slowly; they just need to be opened a bit so propane will slowly flow and pressurize the lines, then they can be opened the rest of the way as quickly as desired.

I use this stove burner technique as required after running out of propane to get the lines purged before expecting any other appliance to run properly.
