Questions

Is there a KiCad symbol and footprint for the SMBJ85A?

Yes. 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 SMBJ85A?

SMB, with 5 pins. Its footprint is drawn on this page.

Where can I order the SMBJ85A?

JLCPCB lists it as part C55223032, with 3,000 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ85A?

Parts like it in the library: the 1.0SMBJ85CA by MDD, the SMBJ85A by TECH PUBLIC, the SMBJ85CA by TDD and the SMBJ85A by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
