They do have this, its called EasyEDA. In my experience its not as good as kicad and definitely not as good as the 'professional' tools like cadence and altium. Our tool does basically do that though! We have a big library of kicad components that can be used in your designs as well as an import just about any JLC component just using its JLCPN. We love their service, would love to see that model proliferated to other companies also, so hard to beat having parts available and in stock.
