Because the movie characters are restricted greatly and it is confirmed they can't use him. They can after the change in executives post BvS. Otherwise we wouldn't get Superman or Deadshot's cameo. Barry Allen is obviously staying in the main cast even despite the release of Justice League. And it's not like Jesse Eisenberg is returning so the "actor confusion" can happen.

There is nothing stopping them from adapting Lex.
