Is there a KiCad symbol and footprint for the TS421IST?
Yes. The symbol is EasyEDA_Cloud:TS4902IST and the footprint EasyEDA_Cloud:MSOP-8_L3.0-W3.0-P0.65-LS4.9-BL-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the TS421IST?
MiNiSO-8, with 8 pins. Its footprint is drawn on this page.
Where is the TS421IST datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the TS421IST?
JLCPCB lists it as part C19557524, with 0 in stock; the sellers' links on this page open their listings.
What can replace the TS421IST?
Parts like it in the library: the NJM2770RB1-TE1# by Nisshinbo Micro Devices Inc. and the TS486IST by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
