I don't think Arsenal have had that terrible a transfer window, certainly not as bad as some people are suggesting anyway. I think what we're seeing is Arsenal paying for and trying to reverse the mistakes of the last few seasons. They tried the short term plan with your Willian's and Luiz's and it's backfired. They've got underperforming, ageing players on big contracts who they're stuck with.
When looking at Arsenal's signings you need to look at the situation the club find themselves in right now. Odegaard, Ramsdale and White aren't the finishing touches to a side that are expected to challenge for major honours. They're putting together a nucleus of a squad which they can build on in the future. I can't comment on Ramsdale as I've not seen him enough but White is a very good CB and Odegaard is a very talented player too - they're not going to transform Arsenal and without better players around them they might struggle from time to time but Arsenal aren't in a position to make transformative signings right now. The key for Arsenal will now be to get back into Europe with this group and then build on this platform, signing an aerially dominant CB to partner White, a dominant CM (maybe that's Partey) to play behind Odegaard, Smith Rowe, Saka etc and sign a long term replacement for Aubameyang.
