Would propofol given during surgery induce vt in brugada syndrome patient ?

It could: There is a relationship between giving propofol and some specific adverse outcomes in those individuals who develop an acute Brugada syndrome pattern but it does not necessarily mean that it would happen that way.

Brugada & anesthesia: The risk of a drug causing or worsening a cardiac rhythm disturbance is a concern with some anesthetic drugs. For patients w/ Brugada syndrome, this is a much more significant issue. In a study of 57 patients w Brugada, a single dose of propafol did not cause problems, but extreme caution is advised for general anesthesia of Brugada patients especially w prolonged propafol infusion.
