Questions

Is there a KiCad symbol and footprint for the MM1Z18?

Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MM1Z18?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where is the MM1Z18 datasheet?

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

Where can I order the MM1Z18?

JLCPCB lists it as part C107584, with 10,825 in stock; the sellers' links on this page open their listings.

What can replace the MM1Z18?

Parts like it in the library: the BZT52C18 by GOODWORK, the MMSZ5248B by hongjiacheng, the MM1W18 by Shandong Jingdao Microelectronics and the MMSZ5248B by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
