Questions

Is there a KiCad symbol and footprint for the VIPER38LD?

Yes. The symbol is Analog & Interface:VIPER38LD and the footprint Package_SO:SOIC-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 VIPER38LD?

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

Where is the VIPER38LD datasheet?

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

Where can I order the VIPER38LD?

JLCPCB lists it as part C222371, with 24 in stock; the sellers' links on this page open their listings.

What can replace the VIPER38LD?

Parts like it in the library: the SG3525M/TR by HGSEMI, the VIPER26LD by STMicroelectronics, the HR1000AGS-Z by Monolithic Power Systems and the HR1001BGS-Z by Monolithic Power Systems. Check their datasheets: a part that fits the footprint may still differ in its ratings.
