Questions

Is there a KiCad symbol and footprint for the LM4666SD?

Yes. The symbol is 4ms_IC:LM4666 and the footprint EasyEDA_Cloud:WSON-14_L4.0-W3.0-P0.50-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4666SD?

WSON-14-EP(3x4), with 15 pins. Its footprint is drawn on this page.

Where is the LM4666SD datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM4666SD?

JLCPCB lists it as part C2863693, with 26 in stock; the sellers' links on this page open their listings.

What can replace the LM4666SD?

Parts like it in the library: the LM4953SD by Texas Instruments, the LM4953SDX by Texas Instruments, the LM4928SD by Texas Instruments and the LM4992SD by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
