Questions

Is there a KiCad symbol and footprint for the LT1777CS?

Yes. The symbol is Regulators:LT1777 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 LT1777CS?

SOIC16, with 16 pins. Its footprint is drawn on this page.

What can replace the LT1777CS?

Parts like it in the library: the CD4017BM(LX) by lingxingic, the DAC0800LCMX-TUDI by Tudi, the TL494-SOP-16 by DDF and the SG3525AES by GREENMICRO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
