You can argue that for 2020 (against Miami again), but it wasn't that extreme. The only time Bucks defense got destroyed was when the Heat shot threes better than 2017 Warriors...
Okay so bottom line, you're looking to chalk this up to shooting luck, and I'm reluctant to do that. We may not be able to come together on this, but I can understand why a knowledgeable basketball observer would conclude what - I believe - you have.
I'm curious how you see the fact that Miami did this in 2 of their 4 series in these 2023 playoffs though. If something like this truly seem like, oh I don't know, a "one in a thousand" situation, it would be easier for me to chalk it up to luck. Having 2 "one in a thousand" events in 4 tries though? That's tough.
I don't want to come off as if I'm saying there isn't any randomness in play here. Run the Boston-Miami series in 10 universes, maybe Boston wins in 9 of them. The better team doesn't always win, and quite literally if we re-ran these playoffs, I wouldn't favor Miami to get through the Eastern Conference.
But that's different from me treating what happened as a meaningless event. What happened didn't just happen, it's something teams knew could happen, and they plan accordingly, and look to build a team balancing the risks. If teams expected opponents could shoot like this all the time, well then they'd build their own teams looking to take 3-point defense all the more seriously. And this I think leads us to an important general question that's also central to what we're specifically talking about in our example:
Were the Bucks looking to take 3-point defense more seriously than they do, how do we think that would effect Brook's role in their grand scheme? 
Perhaps the true answer is something that doesn't reflect negatively on Brook, but I think it's clear why I would be concerned.
 
The problem is that you can't really stop a team that shoots 45% from three point line on 35 attempts. Not when your offense disappoints. As I said - it wasn't the matter of Heat creating a lot of open threes - they had below average volume in that series and whole playoffs in that regard. No, it was the case of the Heat getting incredibly hot on tough shots and when it happens, you can't do much to stop such offense. 
I get that it's tough to pick Brook after such an underwhelming team performance from statistical perspective, but I just don't have any impression that Brook disappointed in the series. I'd argue it was Bud who did the worst job from schematic perspective, but I think we can agree to disagree at this point.
 
Agree that we can agree to disagree, but I will say that that first line of yours I bolded gets to the heart of the matter.
When you say "can't really stop a team that shoots 45% from three...", I would say that by definition, if they're shooting 45% from three, then you failed to stop them, but that doesn't mean that they couldn't have been made more likely to be stopped.
The question then becomes whether it's complete luck as to whether something like this happens or not. 
If I do a search based on your numbers - of the teams who have had the most games allowing 45% from 3 on 35+ 3PA from '18-19 to '22-23 (the Bucks' Bud years) across those regular seasons, here's the leaderboard:
1. Portland 33
(tie) Milwaukee 33
3. Charlotte 32
4. Orlando 31
(tie) New Orleans 31
(If I include the playoffs the Bucks grab the lead completely to themselves, but of course that's not really fair given that Portland, Charlotte, Orlando & New Orleans haven't been good enough to play all that much in the playoffs.)
It's been a known thing for forever that the Bucks' defensive strategy involved them prioritizing the interior over the perimeter, and yeah, there's data that shows the consequence of this. I'll acknowledge that the Bucks looked better on this front this season, and maybe you can argue that makes all of this no longer relevant, but all of this gets into why I'm reluctant to act as if this stuff was just luck in these playoffs.
Was there luck involved? Absolutely.
Do the Bucks beat the Heat more than half the time in normal circumstances? Quite possibly.
But I have issues with treating less-than-majority outcomes as meaningless when it's clear that some teams are more prone to those outcomes than others.
