Questions

Is there a KiCad symbol and footprint for the TL2842D?

Yes. The symbol is EasyEDA_Cloud:TL3844DR and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TL2842D?

SOIC-14, with 14 pins. Its footprint is drawn on this page.

Where is the TL2842D datasheet?

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

Where can I order the TL2842D?

JLCPCB lists it as part C485088, with 50 in stock; the sellers' links on this page open their listings.

What can replace the TL2842D?

Parts like it in the library: the UC2843ADTR by Texas Instruments, the UC2844BD by onsemi, the UC3842BD by onsemi and the UC3844BD by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
