Questions

Is there a KiCad symbol and footprint for the PST4056?

Yes. The symbol is EasyEDA_Cloud:TP4066-4.2V-DFN228 and the footprint EasyEDA_Cloud:DFN-8_L2.0-W2.0-P0.50-BL-EP1.5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PST4056?

DFN-8-EP(2x2), with 9 pins. Its footprint is drawn on this page.

Where is the PST4056 datasheet?

phaetonsemi publishes it: the Datasheet link on this page opens it.

Where can I order the PST4056?

JLCPCB lists it as part C516396, with 0 in stock; the sellers' links on this page open their listings.

What can replace the PST4056?

Parts like it in the library: the LGS5602DA by Legend-Si and the MAX8808XETA-T by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
