Thanks. This looks interesting. It looks like at least the start of LC0's PV is SF-non-dev's 2nd line with almost the same score.

Louis, can you see what SF-dev or Lc says??

I'm beginning to wonder if it really is a draw.

In the SF-non-dev, depth=50 version of this line (they agree for 8 plies), the position after 46...Bxh4+ is

[d]8/6k1/6r1/3P4/4P2b/5P2/PPN3K1/8 w - - 0 47

and after 54...Rxb2 it is

[d]8/5k2/8/3PP3/5P2/P7/1r2K3/8 w - - 0 55

which is a tablebase draw.

I'll look at Leela's lines next.

What is it not seeing that SF-dev is? And what is Leela's PV (and eval)?
