Questions

Is there a KiCad symbol and footprint for the CH558T?

Yes. The symbol is EasyEDA_Cloud:CH558T 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 CH558T?

SSOP-20-208mil, with 20 pins. Its footprint is drawn on this page.

Where is the CH558T datasheet?

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

Where can I order the CH558T?

JLCPCB lists it as part C139616, with 33 in stock; the sellers' links on this page open their listings.

What can replace the CH558T?

Parts like it in the library: the PIC18F13K22-I/SS by Microchip Technology, the PIC18F14K22-I/SS by Microchip Technology, the PIC18F15Q40-I/SS by Microchip Technology and the PIC18F16Q40-I/SS by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
