Questions

Is there a KiCad symbol and footprint for the TL494IDG4?

Yes. The symbol is Regulator_Controller:TL494 and the footprint Package_SO:SOIC-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TL494IDG4?

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

Where is the TL494IDG4 datasheet?

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

Where can I order the TL494IDG4?

JLCPCB lists it as part C1530307, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TL494IDG4?

Parts like it in the library: the TL594CD by Texas Instruments, the SG2524DRE4 by Texas Instruments, the SG3524DRE4 by Texas Instruments and the TL494CDRE4 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
