LLMs help already a lot because plenty of normal people do not have programming skills. Evaluating test results is a lot harder if you do not know how to program or how to use a computer.

But LLMs compute requirement is so high that it pushes the boundaries of compute, memory and memory bandwidth which is fundamental for curing diseases.

LLMs math / neural networks can and are used for medical research. Simulating a whole body with proteins, cells etc. will bring us the breakthrough we need.

Nothing in modern medicin research is withoout compute.

AlphaFold def helps researchers around the globe.

More accurate biological simulations could help but there is zero reason to expect that LLMs will be an effective platform for such simulations. That's pure speculation and probably wrong.
