[global] Fix alerts for mixing implicit and explicit returns

[TurboTurtle]

This commit resolves the alerts generated by GitHub code scanning for mixing implicit and explicit returns. In most cases this is simply changing empty or implicit returns to return None, while in a few other places the return logic is slightly reworked.

I have not manually tested these changes yet since I am doing this from the airport on a new employer's Mac (FSM, have mercy this is painful), so I'm leaning heavily on the CI here.

Once back in a sane development environment I'll take another sanity pass through here but I think these should overall be safe and trivial.
