Questions

Is there a KiCad symbol and footprint for the LM2575IN?

Yes. The symbol is EasyEDA_Cloud:TL2575-ADJIN and the footprint Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2575IN?

PDIP-16, with 16 pins. Its footprint is drawn on this page.

Where is the LM2575IN datasheet?

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

Where can I order the LM2575IN?

JLCPCB lists it as part C1355968, with 5 in stock; the sellers' links on this page open their listings.

What can replace the LM2575IN?

Parts like it in the library: the LM78S40CN by Texas Instruments, the UC3856N by Texas Instruments, the LTC1149CN-5#PBF by Analog Devices and the MAX743EPE+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
