Hello Daniele
As the manual states:

With -v you are matching the *lines* that don't contain "[a-z]{1}[0-9]+\.ko$",
not the *portion of the line* which doesn't match.
For removing lines which end that way I would recommend you to simply replace
your grep with sed, ie.
sed -E 's/[a-z]{1}[0-9]+\.ko$//'
(add -n and p flag to ignore lines not ending that way)
Best regards
