Overview
The TL431 is a voltage Reference made by ZRE in a SOT-23 package with 3 pins. -25℃~+85℃@(Topr) 1mA 2.5V~36V 50ppm/℃ Adjustable Parallel ±1% SOT-23 Voltage Reference ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AZ432ANTR-TP, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C779770).

Questions
Is there a KiCad symbol and footprint for the TL431?
Yes. The symbol is EasyEDA_Cloud:AZ432ANTR-TP and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL431?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the TL431 datasheet?
ZRE publishes it: the Datasheet link on this page opens it.
Where can I order the TL431?
JLCPCB lists it as part C779770, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TL431?
Parts like it in the library: the LM431BIM3/NOPB by Texas Instruments, the LM4040B20IDBZ by Texas Instruments, the ZTL431AFFTA by Diodes Incorporated and the TLVH431AQDBZRG4 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
