Questions

Is there a KiCad symbol and footprint for the LM2578AM?

Yes. The symbol is Regulator_Switching:LM2578 and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM2578AM?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM2578AM datasheet?

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

Where can I order the LM2578AM?

JLCPCB lists it as part C202137, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM2578AM?

Parts like it in the library: the XL1509-5.0E1 by XLSEMI, the XL1509-ADJE1 by XLSEMI, the XL1410E1 by XLSEMI and the MC34063AD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
