That execve() is pretty obviously coming from system().  Try writing a
little C program that calls system() and strace that, maybe the
library is supplying the "/bin/zsh -c" part because lesspipe is a
script (which is also undocumented and potentially wrong, since the
script does have a #! line).

You could stop setting LESSOPEN.  I long ago decided the "convenience"
of having gzip files etc. automatically unpacked was not worth the
other side-effects.
