Questions

Is there a KiCad symbol and footprint for the SM6F31AY?

Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-128, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SM6F31AY?

SOD-128, with 2 pins. Its footprint is drawn on this page.

Where is the SM6F31AY datasheet?

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

Where can I order the SM6F31AY?

JLCPCB lists it as part C3700872, with 14 in stock; the sellers' links on this page open their listings.

What can replace the SM6F31AY?

Parts like it in the library: the P6KE36CA by STMicroelectronics, the SMB6F31A by STMicroelectronics, the SMB6F31AY by STMicroelectronics and the P6KE36A by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
