Questions

Is there a KiCad symbol and footprint for the CH9350L?

Yes. The symbol is EasyEDA_Cloud:CH9350L and the footprint Package_QFP:LQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH9350L?

LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the CH9350L datasheet?

WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.

Where can I order the CH9350L?

JLCPCB lists it as part C109472, with 258 in stock; the sellers' links on this page open their listings.

What can replace the CH9350L?

Parts like it in the library: the XR21V1414IM48TR-F by MaxLinear, the FT232HL-REEL by FTDI, the FE2.1 by TERMINUS and the FE1.1 by TERMINUS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
