Questions

Is there a KiCad symbol and footprint for the SMBJ18A?

Yes. The symbol is Diodes:Diode Zener 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 SMBJ18A?

SMB, with 2 pins. Its footprint is drawn on this page.

Where is the SMBJ18A datasheet?

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

Where can I order the SMBJ18A?

JLCPCB lists it as part C6937298, with 27 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ18A?

Parts like it in the library: the SMBJ18A by TECH PUBLIC, the SMBJ18A by PDW, the SMBJ18A by Shenzhen JDT Fuse and the SMBJ18A by SPSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
