Additionally, probing the gates of the FETs shows that there is somehow overlap in the HI and LO drive signals, despite my attempts to tune the voltage sources I am using to generate the PWM signals.
That is likely to be a cause of shoot-through current.

I am not sure if the shoot-through is an artifact of LTSpice or if I am simply wrong with how I have set the PWMs up.
I think it is unlikely to be an LTspice artifact, but something in the models might be responsible.? Large MOSFETs can have significant input (gate) capacitance which can mess things up.? If you probe the signals you generated, do they seem right or do they have the wrong overlap?
