Questions

Is there a KiCad symbol and footprint for the CH352L?

Yes. The symbol is EasyEDA_Cloud:CH352L and the footprint Package_QFP:LQFP-100_14x14mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH352L?

LQFP-100(14x14), with 100 pins. Its footprint is drawn on this page.

Where is the CH352L datasheet?

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

Where can I order the CH352L?

JLCPCB lists it as part C125755, with 79 in stock; the sellers' links on this page open their listings.

What can replace the CH352L?

Parts like it in the library: the CH368L by WCH (Nanjing Qinheng Microelectronics), the AD8197BASTZ by Analog Devices, the CH384L by WCH (Nanjing Qinheng Microelectronics) and the TSB12LV32TPZEP by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
