Question Why does the Sapphire Pulse RX 5500 XT require an 8 pin connector if its TDP is 135w ?

TDP is a thermal measurement for cooling, not power usage.

Now Sapphires site doesn't actually say TDP(and rightly so) they call it power power consumption. 135w is likely the average at 100% usage but there can be spikes above that(transient loads) they went from being limited to 150w(slot+6-pin) to 225w(slot +8 pin) for extra padding for transients and potentially further overclocking without the possibility of having to go out of spec on the slot or cable.
