Jeez, all this "LLM avoidance" is so horribly silly. We will remember it in 10 years like we now remember the decision to setup our great European cookie popup laws. As well intentioned, but very detrimental.
You will not stop scrapers. Period. They will just pay for a service like firecrawl that will fix it for them. Here in Poland one of the most notorious sites implementing anti-bot tech is our domestic eBay competitor allegro.pl. I've been locked out of that site for "clicking too fast" more than once. They have the strictest, most inconvenient software possible (everyone uses the site). And yet firecrawl has no problem scraping them (although rather slowly).
Second argument against these "protections" is, there are people behind bots. Many bot requests are driven by a human asking "find me cheapest rtx5060 ti 16gb" today. If your site blocks it they will loose that sale.
