Is there a KiCad symbol and footprint for the REF3318AIDBZ?
Yes. The symbol is Regulators:REG3 1IN-2OUT-3GND and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the REF3318AIDBZ?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the REF3318AIDBZ datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the REF3318AIDBZ?
JLCPCB lists it as part C115877, with 5,281 in stock; the sellers' links on this page open their listings.
What can replace the REF3318AIDBZ?
Parts like it in the library: the RS3112-1.8XSF3 by Jiangsu RUNIC Tech, the REF3318AIM3/TR-HG by HGSEMI, the ISL60002DIH318Z-TK by Renesas Electronics and the REF318SOT233 by analogysemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
