Whether this distinction is relevant is up to you, but I think we can safely say agents do not lie in the human sense of the word, because they don't intend to deceive (in fact, they aren't capable of "intending" anything in the human sense of the word, much like a BASIC program doesn't "intend" to PRINT "HELLO WORLD").
Our very human minds can perceive intent, because that's what we humans do, which is unrelated to what the agent is actually doing.
> If you ask the dice "what's 2 + 2?" do consider it meaningful to say "the dice told the truth" if you happen to roll a 4?
No, and neither do I consider it meaningful to say they lied if they roll a 5.
Dice neither tell the truth nor lie; they aren't beings capable of being truthful or deceitful, they are mechanical devices that can be statistically suitable or unsuitable for a given application.
