Questions
Is there a KiCad symbol and footprint for the CH341T?
Yes. The symbol is EasyEDA_Cloud:CH341T and the footprint Package_SO:SSOP-20_5.3x7.2mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CH341T?
SSOP-20-208mil, with 20 pins. Its footprint is drawn on this page.
Where is the CH341T datasheet?
WCH (Nanjing Qinheng Microelectronics) publishes it: the Datasheet link on this page opens it.
Where can I order the CH341T?
JLCPCB lists it as part C23971, with 979 in stock; the sellers' links on this page open their listings.
What can replace the CH341T?
Parts like it in the library: the CH376T by WCH (Nanjing Qinheng Microelectronics), the MCP2200-I/SS by Microchip Technology, the CH345T by WCH (Nanjing Qinheng Microelectronics) and the MCP2210-I/SS by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
