Nope, just regular singlespeak. Violence can plainly be non-physical.

This isn't a description of doublespeak. An example of doublespeak could be someone using their speech to call for violence against others and then saying speech can't be violence.
Why would you even need to say «call for violence» if speech were violence in itself?
No one is opposing the fact that speech can be used to call for violence, but that doesn’t make the speech itself violence. The speech part of it is the «call for» or «incitement to» or even «lead to». But we must not mix up cause and effect.
Using speech to call for violence against someone is intermediated by the minds and bodies of listeners, who have their own free will, their own intelligence, and their own responsibility.
In U.S. law we have the "imminent lawless action" test from Brandenburg v. Ohio as one of the main tests for whether speech can be regulated because of its likelihood of successfully encouraging others to break the law.
Even when speech fails the Brandenburg test, it is still not literally considered a form of violence, but something else like incitement (or sometimes part of a conspiracy or criminal enterprise or something).
All of those legal discussions are pretty much expressly about not conflating speech with violence, even if speech sometimes has a role in encouraging people to commit violence.
Law uses language in a way that is different from how laypeople use it. I am not concerned that I would be unable to convince a judge that it's violence because I know it's the judge's job to think of violence as having a specific, narrow, unchanging (except under certain circumstances) meaning. Outside that context, violence can take the form of speech.
I see it as a great sign of maturity and civilization that we can make a firm distinction between words and violence. To me, the judge's "job" you mention is part of that.
This distinction could be something that has to be actively learned (like, maybe most people in human history would have instinctively resorted to physical violence over an insult). But if so, actively learning it is a great thing.
This is an example of how the violence of speech is often minimized and dismissed. Causing hurt feelings is violence, particularly doing so intentionally.
