You believe X. Why? Because of Y. Why believe Y? Because of Z. This goes on forever (infinite regress). Three philosophical positions attempt to solve this: (1) Foundationalism — some beliefs need no justification. (2) Coherentism — beliefs justify each other in a web. (3) Infinitism — the chain can be infinite. Evaluate each. Then: how does an AI language model 'justify' its outputs? Does it face the same problem?
