would the teutonic order continue to grow
No. This battle wasn`t even as decisive, as some people think.
Well a decisive enough victory could end the union between Poland and Lithuania, no?

Decisive Polish-Lithuanian victory might end the union, Teutonic victory would only make union stronger. In 1431 Poland and Lithuania fought war, because Grand Duchy became very strong, and Lithuanian nobility chosen Grand Duke against will of Poland, thus braking Union of Horodło. With danger from stronger Teutonic Order it wouldn`t happen.
Would the Order actually avoid the civil wars it historically endured following the defeat? It's an open question if the Order wins but isn't structurally stronger?
