Questions

Is there a KiCad symbol and footprint for the TL431G-AE2-R?

Yes. The symbol is EasyEDA_Cloud:TL431_C55807316 and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TL431G-AE2-R?

SOT-23-3, with 3 pins. Its footprint is drawn on this page.

Where is the TL431G-AE2-R datasheet?

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

Where can I order the TL431G-AE2-R?

JLCPCB lists it as part C71129, with 38,939 in stock; the sellers' links on this page open their listings.

What can replace the TL431G-AE2-R?

Parts like it in the library: the TL431BQDBZR by Texas Instruments, the ATL431BIDBZ by Texas Instruments, the TL431BCDBZR by Texas Instruments and the NCP432BVSN by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
