If I don't want to use the Tj Sense pin (6) on THS3491IRGT, can I leave it floating? Do I need the 0.1uF cap on it that the EVM has?
Thanks,
Matt

Hello Matt,
You may leave this pin floating.
Tj Sense pin (6) on the THS3491IRGT is internally connected to the reference pin (REF) or pin 5 (GND) on RGT package which must be connected to GND.
Thank you,

No problem! No, you do not. We always put these decoupling caps on digital, power-down, or power-supply pins to mitigate the amount of noise and ringing at the pin. But, if the pin is not being used, then it is not necessary.
