Questions

Is there a KiCad symbol and footprint for the LD1117AS18?

Yes. The symbol is Celestial_Power_Linear_VReg:ST LD1117 and the footprint EasyEDA_Cloud:SOT-223-3_L6.7-W3.7-P2.30-LS7.0-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LD1117AS18?

SOT-223-3, with 4 pins. Its footprint is drawn on this page.

Where is the LD1117AS18 datasheet?

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

Where can I order the LD1117AS18?

JLCPCB lists it as part C2845037, with 4,332 in stock; the sellers' links on this page open their listings.

What can replace the LD1117AS18?

Parts like it in the library: the AMS1117-1.8 by UMW, the AMS1117-1.8 by Advanced Monolithic Systems, the LD1117-1.8 by UMW and the AMS1117-1.8V by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
