This is the kicad template i use for my projects. The latest addition is a buildoutputs.py automating picture generation, 3d models and sch/prints, Gerbers ETC! Pretty sweet!
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-523, both drawn on this page. PCBKit places them on a board for you when you design with it.
SOD-523, with 2 pins. Its footprint is drawn on this page.
ROHM Semiconductor publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C209620, with 14,347 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the BZX584C5V1 by hongjiacheng, the LM5Z5V1T1G by Leshan Radio (LRC), the MM5Z5V1 by CBI and the MM5Z5V1T1G by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
