Does this work in the other direction? as in, power input on the 4 pin side connected to a control board, with 5v power delivered to the usb end

I have not tried this, but I should work. I mean, I don't see why it would not work. USB data & power can travel both ways on wires

Will this work to plug govee lights into the usb input on a tv?

I am not sure about govee lights, but this adapter transfers power to other USB devices.
