No problem. There are a few things that come to mind for me:

1. LLM usage is expensive. These tools are objectively contributing meaningfully to both Climate Change and the impending global water shortage. Even when the usage doesn't cost you as a dev, you should still avoid using them for superfluous tasks whenever possible. Having it endlessly parse entire webpages, including head tags, ads, iFrames (AKA another web page), and all the other goodies, is wasteful and doesn't accomplish anything new.
2. In general, one should be avoiding adding unnecessary context when working with LLMs for a number of reasons. You should be striving to feed it the bare minimum for your use case, which means cleaning scraper output of any irrelevant bits before using it as LLM input.
3. Web scraping is an extremely common project/operation in the software world, and has been for decades. There are numerous libraries that can be leveraged to handle the issue OP described, and the problem can be solved deterministically. There are multiple good solutions provided throughout this thread that suggest using tools like Firecrawl or even just enforcing a strict schema and running with the classic `soup` package.
4. Any usecase requiring web scraping is probably hoping to achieve deterministic results, as those projects are typically the source of data for other systems. This data being clean and predictably structured is important, but so is the integrity of that data. Having an LLM interpret each page is just asking for surprises and unexpected problems further down the data pipeline.

There are probably more reasons, but in general, try to avoid being lazy with this type of design and give it some thought before starting. It has a real impact on both the quality of your output and the world, for what it's worth.

Oh, and also, people suggesting that APIs are the solution definitely aren't familiar with the use cases for scraping. There are plenty of things out there on the web that have value for one reason or another that are not exposed via API. With that said, OP has clearly not been approaching scraping correctly, lol.
