Questions

Is there a KiCad symbol and footprint for the LP3950SL?

Yes. The symbol is EasyEDA_Cloud:LP3950SL_NOPB and the footprint EasyEDA_Cloud:TLGA-32_L5.5-W4.5-P0.50-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LP3950SL?

TLGA-32, with 32 pins. Its footprint is drawn on this page.

Where is the LP3950SL datasheet?

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

Where can I order the LP3950SL?

JLCPCB lists it as part C2679162, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LP3950SL?

Parts like it in the library: the AP3602AKTR-G1 by Diodes Incorporated, the RT9361AGE by Richtek Tech, the MAX16813ATP/V+T by Maxim Integrated (Analog Devices) and the MPQ3369GR-AEC1-Z by Monolithic Power Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
