Questions

Is there a KiCad symbol and footprint for the SM6T33A?

Yes. The symbol is Diode:SM6T33A and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SM6T33A?

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

Where is the SM6T33A datasheet?

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

Where can I order the SM6T33A?

JLCPCB lists it as part C133690, with 4,081 in stock; the sellers' links on this page open their listings.

What can replace the SM6T33A?

Parts like it in the library: the P6SMB33CA by hongjiacheng, the SM6T33A by FUXINSEMI, the P6SMB33A by Littelfuse and the P6SMB33A by FUXINSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
