Does not reproduce for me: Running with GB layout as
kitty --config=NONE --debug-input kitten show-key
Pressing control+backtick (key to the left of 1) gives me backtick, as expected. Pressing control+\ (key to the right of ] and above return gives ^\ as expected.
Note that different terminals map control+backtick to different things, kitty maps it to backtick in legacy encoding. For proper usage of control+backtick use the kitty keyboard protocol, for example:
kitty kitten show-key -m kitty
from kitty.

Upon further testing, the problem is only with the GBPC layout, and can be observed both with an ISO keyboard and with an ANSI keyboard.
I've run a test protocol, using kitty --config=NONE --debug-input kitten show-key.
This test uses two different physical keyboards, the first one an ISO GB keyboard, the second is an ANSI US keyboard.
For each keyboard, I test three different layouts: US, GB, GBPC
For the ISO keyboard, I test three physical keys: Non-US Backslash, Non-US Hash, Backtick
For the ANSI keyboard, I test two physical keys: Backslash, backtick
The six Control-Backslash events are isolated here (full test below):

For my ISO keyboard, I test with three physical keys:
NUBS = Non-US Backslash
NUHS = Non-US Hash
Backtick
ISO Keyboard, GBPC Layout:
NUBS -> Seen as '\'
Backtick -> Seen as '`'
NUHS -> Seen as '#'
Test pattern:
(Logical backslash/physical NUBS) -> Unmodified, then Control-modified
(Logical backtick/physical backtick) -> Unmodified, then Control-modified
(Logical hash/physical NUHS) -> Unmodified, then Control-modified

On my mac with GBPC layout pressing the backslash key generates # in all
applications including kitty and
pressing the control + backslash key also generates # which is correct
since there is no encoding for ctrl+# in legacy mode.

This bug report is supposed to be about the handling of control-backslash in the GBPC layout.
If you're using an ISO keyboard with GBPC layout, that key is generated by pressing NUBS, or Non-US Backslash.
If you're using an ANSI keyboard with GBPC layout, that key is generated by pressing the backtick key.
Assuming that you're testing with an ANSI keyboard with GBPC layout, this is the log that comes from pressing control-backtick, which simulates the control-backslash of an ISO keyboard using GBPC layout:

You can see that the unmodchars is seen as backslash, that that the mods: ctrl exists, and yet it is:
sent key as text to child: `

Because cocoa is calling insertText with ` as the text for that key
event. Nothing kitty can do here, it takes insertText inserting text
as meaning Apple wants the key to insert text, since that is what its
native framework does.

I verified this by exporting out the two keyboard layouts from the system, and you're absolutely right. The keyboard layout specifies that control-backslash should be treated as a backtick.
Given that, however, I looked through the keyboard mapping to see how control-backslash is actually mapped, and it turns out that the way to generate a control-backslash in this layout is by hitting control-hash.
I verified this by opening Terminal.app and starting cat before hitting control-hash, and the control-backslash character was successfully output.
However, when I opened kitty, I do not get the correct mapping of control-hash pressed to control-backslash output:

It seems like the kitty code is "correctly" interpreting all keys that generate insertText, but manually (mis-)interpreting doCommandBySelector based on the original key pressed.
I have a workaround, I will create a custom keymap based off of GBPC (since I never want to use control-backslash to mean backtick).
