The rocket engines are not just steel, but the alloys they are made of are pretty tough, they would not be pulverized. Almost all of Starship is made of stainless steel, though. There's little or no fancy carbon fiber, etc. But there is one possible component that could in fact result in small debris and dust blown miles away from launch: The heat shield tiles.
