I'm not sure how to express how I feel about this without using a massive amount of profanity. First things first, chatbots should not be trusted. They're text extruders. That's all. Grok should be trusted less than most because it's tuned to express opinions held by Musk and not to more accurately represent reality. Further, having the bot "apologize" is simply anthropomorphizing software to increase people's trust in it, even when it did something reprehensible.
