> 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.

It'd be bonkers to anthropomorphize dice.
