webp should be built in if it was found at build time. What do you mean by
"broken"? Does it report webp support ("oiiotool --help", look at bottom) but
it doesn't seem to work, or do you suspect you didn't build with webp support
at all?
4:4:4 -- you were close! --iconfig is configuration hints for input. For
output, you just need to set a regular metadata output. So I think this would
work
oiiotool ... --attrib "jpeg:subsampling" "4:4:4" out.jpg
