Q: Is there a KiCad symbol and footprint for the TS20?

Yes. The symbol is EasyEDA_Cloud:TS20 and the footprint Package_SO:TSSOP-28_4.4x9.7mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

Q: What package is the TS20?

TSSOP-28, with 28 pins. Its footprint is drawn on this page.

Q: Where is the TS20 datasheet?

AD Semicon publishes it: the Datasheet link on this page opens it.

Q: Where can I order the TS20?

JLCPCB lists it as part C95876, with 3 in stock; the sellers' links on this page open their listings.

Q: What can replace the TS20?

Parts like it in the library: the CBM7021 by Chipsbank. Check their datasheets: a part that fits the footprint may still differ in its ratings.
