Is there a KiCad symbol and footprint for the A7986ATR?

Yes. The symbol is EasyEDA_Cloud:L7980TR and the footprint EasyEDA_Cloud:HSOP-8_L5.0-W4.0-P1.27-LS6.2-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the A7986ATR?

SOIC-8, with 9 pins. Its footprint is drawn on this page.

Where is the A7986ATR datasheet?

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

Where can I order the A7986ATR?

JLCPCB lists it as part C2970022, with 8 in stock; the sellers' links on this page open their listings.

What can replace the A7986ATR?

Parts like it in the library: the TPS54327DDAR by Texas Instruments, the TPS5432DDAR by Texas Instruments, the TPS54428DDAR by Texas Instruments and the PAM2320BECADJR by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
