Yes they are, though not in isolation. Additional mechanisms are needed to inject ground truth reliable knowledge into the LLM context. Don't ask an isolated LLM about facts and expect no hallucinations. Instead, use ChatGPT with search plug-in, Bing search, Perplexity.ai or Phind.com (Im sure there are others). Once reliable truth available to the LLM via context, hallucinations go down _significantly_ to the point where (to me at least) it's no longer really much of an issue.
