Questions

Is there a KiCad symbol and footprint for the LM4950TSX?

Yes. The symbol is Amplifier_Audio:LM4950TS and the footprint Package_TO_SOT_SMD:TO-263-9_TabPin5, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM4950TSX?

TO-263-9, with 9 pins. Its footprint is drawn on this page.

Where is the LM4950TSX datasheet?

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

Where can I order the LM4950TSX?

JLCPCB lists it as part C94941, with 1,327 in stock; the sellers' links on this page open their listings.

What can replace the LM4950TSX?

Parts like it in the library: the LM4755TSX by Texas Instruments and the LM4950TS by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
