Questions

Is there a KiCad symbol and footprint for the LM4953SD?

Yes. The symbol is EasyEDA_Cloud:LM4953SD_NOPB 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 LM4953SD?

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

Where is the LM4953SD datasheet?

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

Where can I order the LM4953SD?

JLCPCB lists it as part C4991284, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM4953SD?

Parts like it in the library: the LM4666SD 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.
