Well, no, it won't, because you are asking for an lsearch lookup rather
than a NIS lookup. The syntax of a NIS lookup is
${lookup{key}nis{NIS-full-map-name}{yes-string}{no-string}}
The Exim manual says:
nis: The given file is the name of a NIS map, and a NIS lookup is done
with the given key, without a terminating binary zero. There is a
variant called nis0 which does include the terminating binary zero in
the key. This is reportedly needed for Sun-style alias files. Exim
does not recognize NIS aliases; the full map names must be used.

A guess:
${extract{1}{:}{${lookup{$2}nis{not-just-passwd}}}}
$value is the default; you can omit it. I can't remember what you have
to say for the full map name, but I think it is more than just "passwd".
Let me see if I can find a NIS example -- aha! There is one in the Exim
book:
data = ${lookup{$local_part}nis{mail.aliases}}
