LLMs do contain conceptual representations and LLMs are capable of abstract reasoning. This is trivially provable by asking them to reason about something that is a) purely abstract and b) not in the training data, e.g. "All floots are gronks. Some gronks are klorps. Are any floots klorps?" Any of the leading LLMs will correctly answer questions of this type much more often than chance.
