LLM’s are search engines by their nature, but on top of that they have search engines they reference, they have powerful grepping and search tools to iterate through those results come up with the prevailing theories and outliers and present that as an organized report to you[…]

This is completely wrong, you need to read about how LLMs actually work.
While they can give the appearance of searching, they are not at all search engines.
What an LLM does when it processes a text is adjust some internal weights, nothing more.
Whenever you ask it to search or summarize it generates text according to your query and its weights, not to the original text, and there is absolutely no guarantee that it will correctly do what you asked.
They are a really interesting technology, but currently have zero usefulness as a search engine or summarizer, because the often omit actual results and/or hallucinate incorrect results.
Seriously, read about it, if you are trusting LLM output as factual, you are absolutely being misled.
