Wait, does the judge accept each request? I thought at this point LaLiga was giving the ISPs the ranges directly. Plus it's not only Telefonica/O2, this season (started 2 weeks ago) it's also Vodafone, Digi and MasOrange.

And they don't deny doing it, they claim they block Cloudflare because they host piracy, child pornography (how would they know, did they search for it specifically?) and other illegal stuff and their response is basically "complain to Cloudflare" or "those blocks affect only 4 nerds [using Github, Cloudflare tunnels, Docker Hub...] so we aren't going to change anything".
