Questions

Is there a KiCad symbol and footprint for the 4056?

Yes. The symbol is EasyEDA_Cloud:4056 and the footprint EasyEDA_Pro:esop-8_l4.9-w3.9-p1.27-ls6.0-bl-ep, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 4056?

ESOP-8, with 9 pins. Its footprint is drawn on this page.

Where is the 4056 datasheet?

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

Where can I order the 4056?

JLCPCB lists it as part C392766, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 4056?

Parts like it in the library: the IP2325 by INJOINIC, the CN3153 by CONSONANCE and the ME4059ASPG-N by MICRONE. Check their datasheets: a part that fits the footprint may still differ in its ratings.
