Ribozyms are generally known to have a potential to introduce strand breaks. However, it's indeed a good question whether those may include double strands!
Unfortunately I don't know the answer as it's generally difficult to prove non-existance, but in this paper, they go as far as to imply that translation needed to evolve due to the lack of helicase activity of ribozymes.
In additional literature for helicase activities (which is generally associated with introduction of double-strand breaks), all ribozymes with helicase activity seem to be attached to proteins to be functional. So maybe it's indeed possible, that there are no ribozymes that cut double-strands.
