Questions

Is there a KiCad symbol and footprint for the L4971D013?

Yes. The symbol is EasyEDA_Cloud:L4971D013TR and the footprint Package_SO:SOIC-16W_7.5x10.3mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L4971D013?

SOIC-16-300mil, with 16 pins. Its footprint is drawn on this page.

Where is the L4971D013 datasheet?

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

Where can I order the L4971D013?

JLCPCB lists it as part C2688686, with 2 in stock; the sellers' links on this page open their listings.

What can replace the L4971D013?

Parts like it in the library: the UC3825ADWTR by Texas Instruments, the UC3825ADW by Texas Instruments, the UC3825DW by Texas Instruments and the UC2856QDW by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
