Sadly the recover option Apple put in within the older 2016/17 models was removed. And without a charged battery there is no means to even tell if the problem is the battery or the logic board. Some people have converted an old dead into a pseudo battery emulating via a bench power supply what a real battery would supply to the logic board including the needed BMC sensors. Clearly that's not an option here. You might find an independent repair shop who has the needed battery to even prove or disprove if that's all that's needed. But the service battery warning tells us the batteries days are numbered and they do fail hard like what you encountered here.

I'm betting you only need a battery, and if the logic board is the issue then you'll need to find someone with the needed board repair skills as you can't access the data on your system without the logic board working.
