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.
