I'm sorry to break this to you - but you probably weren't in the training dataset enough for the model to learn of your online presence - yes llms will currently hallucinate when they don't have enough data points (until they learn their own limitations) - but that's not a fundamentally unsolvable problem (not even top 10 i'd say)

there already are models that consider their knowledge and just apologize if they can't answer instead of making shit up. (eg claude)
