An LCD monitor needs to wait for the entire frame to arrive, before it can be processed and then made visible.
Sometimes the monitor will wait for several frames to arrive before it processes them. This enables some temporal processing. When you put a monitor in gaming mode, it disables (some of) this.

If that’s how TFTs worked we wouldn’t have vsync settings in games.

No? Afaik vsync prevents the gpu from sending half drawn frames to the monitor, not the monitor from displaying them. The tearing happens in the gpu buffer
Though I’m not sure how valid the part about latency is. In the worst case scenario (transfer of a frame taking the whole previous frame), the latency of an lcd can only be double that of a crt at the same refresh rate, which 120+ hz already compensates for. And for the inherent latency of the screen, most gaming lcd monitors have less than 5 ms of input lag while a crt on average takes half the frame time to display a pixel, so 8 ms.
