Does KiCad allow to take these delays for each pin into account automatically or do you need to do all that manually?

Edit: it's using the pad property of "pad-to-die-length" if doing it manually, right?

No, it needs to be done manually. It wasn't as tedious as it sounds though. Most of the pins are very close in delay already and there were just few traces that I had to adjust a little.

How is kicad getting along with RF work in 2024, would you say?

I did some prototyping but never got the stage if actually fumbling around with PCBs a few years ago, things seemed to progressing quite well.
