Questions

Is there a KiCad symbol and footprint for the LR431AD?

Yes. The symbol is EasyEDA_Cloud:TL431ACDT-TP and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LR431AD?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the LR431AD datasheet?

Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.

Where can I order the LR431AD?

JLCPCB lists it as part C411183, with 4 in stock; the sellers' links on this page open their listings.

What can replace the LR431AD?

Parts like it in the library: the TL431BCM/TR by HGSEMI, the HT431ARZ by HTCSEMI, the TL431BIDR(UMW) by UMW and the TL1431AIDT-TP by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
