Got an A1534 2015 edition with 250gb SSD and whilst the SSD is detected in internet recovery and also in my test external ssd with mac os it's reading as read-only and I cannot erase it, format it or partition it. I'm presuming this is a dead SSD and assuming this is there any possibility of swapping the chip out with one from another board with a dead CPU or do these require special programming like iPhones? I've done quite a few iPhone 7 NAND replacements and also even fixed one of the HP Streams with a dead SSD before so am confident I can swap the chip successfully!

Apart NAND, you MUST also change the SSD controller.
And that is sandwhich style, like iPhone CPU.

You could try erasing from Linux. I had one case where I wasn't able to erase SSD from macOS (Disk Utility or from Terminal) but after erasing the beginning with dd from Linux, I was able to format and reinstall macOS without issue.
Remember that working on these boards isn't the best idea as CPU can die anytime anyway and customer will blame your work…
