Questions

Is there a KiCad symbol and footprint for the VIPER25LD?

Yes. The symbol is EasyEDA_Cloud:VIPER25LD and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the VIPER25LD?

SO-16, with 16 pins. Its footprint is drawn on this page.

Where is the VIPER25LD datasheet?

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

Where can I order the VIPER25LD?

JLCPCB lists it as part C5267813, with 0 in stock; the sellers' links on this page open their listings.

What can replace the VIPER25LD?

Parts like it in the library: the L6599ATD by STMicroelectronics, the L6599D by STMicroelectronics, the KA7500CDTF by onsemi and the L6598D013 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
