> it becomes noisy and sameish at larger scale or the more you read it.

I absolutely understand where you are coming from, and I agree to a point. If you're of an age where you actually read a printed encyclopedia, the tone and voice of the entire set was sameish as well. The difference is that it didn't sound LLMish like LLM text does. I know that printed encyclopedias would have been vetted by editors, and I feel this is the key difference. Editors not only knew grammar rules, but had that sense of good writing practices that's hard to write down as rules. A piece of text passed through a good editorial review will read human while LLM text reads as LLM text.
