Is there a KiCad symbol and footprint for the TL431CDT?
Yes. The symbol is EasyEDA_Cloud:HT431BRZ and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TL431CDT?
SO-8, with 8 pins. Its footprint is drawn on this page.
Where is the TL431CDT datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the TL431CDT?
JLCPCB lists it as part C283418, with 836 in stock; the sellers' links on this page open their listings.
What can replace the TL431CDT?
Parts like it in the library: the TL431ACD by Texas Instruments, the TL431AID by Texas Instruments, the TL431BVD by onsemi and the TL1431AIYDT by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
