I have recently migrate my sharepoint farm to NSX-T and seems like I can access my sharepoint websites which I was able to do so before migration. Can this be related with multicast traffic from Load Balancing which must to be enabled on one of Tier-0 or Tier-1 routers?

I take it you mean you "can't access" your Sharepoint? There isn't any special enablement of multicast traffic on a T0 or T1, so it might not have had anything to do with it.
