Questions

Is there a KiCad symbol and footprint for the TS4994IST?

Yes. The symbol is EasyEDA_Cloud:TS4994IST and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the TS4994IST?

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

Where is the TS4994IST datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the TS4994IST?

JLCPCB lists it as part C222178, with 6 in stock; the sellers' links on this page open their listings.

What can replace the TS4994IST?

Parts like it in the library: the NS4150B by Shenzhen Nsiway Tech, the LM4890S by IDCHIP, the LM4890SS by IDCHIP and the LN4890MME-G by NATLINEAR. Check their datasheets: a part that fits the footprint may still differ in its ratings.
