You can't 'end with a custodial'! It's a civil, not a criminal, matter. The people in libel actions who have ended up in jail were jailed later in a criminal court for perjury e.g, lying on oath or producing forged documents in evidence court in the libel action.
(Nor do I, for one, think that because some laymen thinks that something is libellous it is.)
Believe me, laymen who feel offended are always threatening to go to a solicitor and solicitors are seeing such people all the time. By the time the solicitor has had a friendly chat and soothed the client , explained the subtleties of libel law, explained just how expensive it is to bring an action for defamation and indicated he wants fees up front, that the client will never get all the costs back, and that even if he wins he may be suing a man of straw, the whole thing normally resolves itself! The solicitor, if the client still wants something done, contents himself with writing a stiff lettter demanding an apology and that is that'
That's why libel actions are so rare !
