Questions

Is there a KiCad symbol and footprint for the TL3843P?

Yes. The symbol is EasyEDA_Cloud:TL3842P and the footprint Package_DIP:DIP-8_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 TL3843P?

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

Where is the TL3843P datasheet?

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

Where can I order the TL3843P?

JLCPCB lists it as part C5211, with 0 in stock; the sellers' links on this page open their listings.

What can replace the TL3843P?

Parts like it in the library: the UC3843BN by STMicroelectronics, the VIPER22A by Minos, the UC2845BN by onsemi and the UC3845BN by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
