Questions

Is there a KiCad symbol and footprint for the TL431ILP?

Yes. The symbol is EasyEDA_Cloud:TP432C249T3 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 TL431ILP?

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

Where is the TL431ILP datasheet?

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

Where can I order the TL431ILP?

JLCPCB lists it as part C903235, with 24 in stock; the sellers' links on this page open their listings.

What can replace the TL431ILP?

Parts like it in the library: the TL1431ACZT by STMicroelectronics, the TL1431ACZ by STMicroelectronics, the TL431K-T92-B by UTC and the LM285Z-2.5-TO-92 by DDF. Check their datasheets: a part that fits the footprint may still differ in its ratings.
