Questions

Is there a KiCad symbol and footprint for the LM431BCZ?

Yes. The symbol is EasyEDA_Cloud:TL431CLP-Z and the footprint EasyEDA_Cloud:TO-92-3_L4.8-W3.7-P1.27-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM431BCZ?

TO-92-3, with 3 pins. Its footprint is drawn on this page.

Where is the LM431BCZ datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM431BCZ?

JLCPCB lists it as part C1575587, with 25 in stock; the sellers' links on this page open their listings.

What can replace the LM431BCZ?

Parts like it in the library: the TL431BILPR by Texas Instruments, the TL1431CLPM by Texas Instruments, the TL431ACLPRE3 by Texas Instruments and the TL431AILPRE3 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
