So it seems the appropriate firmware is ucode11.fw and it cannot be loaded albeit being in /lib/firmware/b43.

I suppose the main problem is that you use a live medium and for whatever reason this prevents loading the firmware. I do not know if it  is due to a different filesystem (squashfs?), permissions on the /lib/firmware/b43 directory, or the system expecting the firmwares in a different directory on a live system, or... etc...
  
I am afraid I do not have the necessary knowledge to further help you.
What I can symply suggest is either:
- use a USB wireless dongle instead of your integrated wireless card. If you use an unofficial Debian Live medium including firmwares, your USB wireless dongle will be recognized straight away, given there is a driver in the Linux kernel.
- delve into the docs of the Debian Live universe ( https://live-team.pages.debian.net/live-manual/ ) and create a tailored Debian Live medium for your needs, including the firmware for your Broadcom wireless card

I fear there is no easier way because all Linux based systems will have by default the same lack of firmwares due to Broadcom policy and I do not think you will find a *BSD based live medium able to deal with your integrated wireless card (I may be wrong)
