Questions

Is there a KiCad symbol and footprint for the CH375B?

Yes. The symbol is EasyEDA_Cloud:CH375B and the footprint Package_SO:SOIC-28W_7.5x17.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CH375B?

SOP-28-300mil, with 28 pins. Its footprint is drawn on this page.

Where is the CH375B datasheet?

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

Where can I order the CH375B?

JLCPCB lists it as part C8962, with 401 in stock; the sellers' links on this page open their listings.

What can replace the CH375B?

Parts like it in the library: the CH376S by WCH (Nanjing Qinheng Microelectronics), the CH341A by WCH (Nanjing Qinheng Microelectronics), the CH341B by WCH (Nanjing Qinheng Microelectronics) and the CH340S by WCH (Nanjing Qinheng Microelectronics). Check their datasheets: a part that fits the footprint may still differ in its ratings.
