Questions

Is there a KiCad symbol and footprint for the SM4T39AY?

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

What package is the SM4T39AY?

SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.

Where is the SM4T39AY datasheet?

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

Where can I order the SM4T39AY?

JLCPCB lists it as part C1975734, with 18 in stock; the sellers' links on this page open their listings.

What can replace the SM4T39AY?

Parts like it in the library: the SMAJ33CA by MDD, the SMAJ33CA by hongjiacheng, the SMAJ33CA by GOODWORK and the SMAJ33CA by 晶导微电子. Check their datasheets: a part that fits the footprint may still differ in its ratings.
