Questions

Is there a KiCad symbol and footprint for the TL431CZ?

Yes. The symbol is EasyEDA_Cloud:TL431IPK-TP and the footprint Package_TO_SOT_THT:TO-92L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TL431CZ?

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

Where is the TL431CZ datasheet?

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

Where can I order the TL431CZ?

JLCPCB lists it as part C283635, with 2,072 in stock; the sellers' links on this page open their listings.

What can replace the TL431CZ?

Parts like it in the library: the ALJTL431A by ALJ, the TL431(0.5%) by UMW, the TL431IZT by STMicroelectronics and the CJ432-TA by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
