If I understand the intent of your message correctly, that's unfortunately not how the law works.
If there is a case that is precedent setting, whether it directly involves bitcoin or not, a bitcoin focused legal fund might want to either offer representation or file an amicus brief to guide the court to making a decision beneficial to Bitcoin Developers.
More than likely, some of these cases would involve developers of alternative projects (as they might be "ahead of the curve" on legal problems) and heading off a strong precedent for other communities would be protective for Bitcoiners in general. As an example, were the developers building Rollups on Ethereum to face a legal threat, since we might one day want similar software for Bitcoin, ensuring a good outcome for them helps Bitcoin.
That said, all organizations must at some point have a defined scope, and it seems the BLDF is primarily focused for now on things impacting the developers of Bitcoin or software for bitcoin specifically. I "trust" the legal team behind BLDF will form a coherent strategy around what is relevant to Bitcoin defense, even if the particulars of a case are not directly about Bitcoin.
