Well for one, every recommended Archaludon set has 56 Speed EVs set aside for Jolly Kingambit, and I think most people would agree that's very reasonable, so we can just go ahead and completely ignore this first image.
52 EVs for jolly Kingambit is literally nothing lmfao, tons of 'mons take out investment far greater than 52 EVs, so I don't see why this is even considered as an argument along the lines of Archaludon not being broken.
Is this an amount small enough that it's an argument for why it's broken? This isn't a point. Archaludon can't maximize its HP, and it's not the biggest downside in the world, but it's not as if this doesn't affect it.
doing nothing to the 'mon if it teras
Forcing the opponent to Terastallize Archaludon early while preserving your own Tera is a form of progress. Archaludon's amazing defensive typing is something it wants to keep, so making Tera gives it one turn of free momentum but overall makes it much more fragile. I use Tera Flying, and suddenly gaining all those weaknesses really hurts. If Archaludon Terastallizes, it's probably lasting that one turn only.
Also, if I don't like the situation, I can just switch out; I resist rocks, I can switch in on a lot of things, and I can recreate the situation again such that I can get the toss up the time it does land a draco meteor on Great Tusk.
Archaludon does not get to run Leftovers on the Draco Meteor set that actually threatens Great Tusk. Even though it resists Stealth Rock, having it up makes a huge difference in this matchup:
252 Atk Great Tusk Headlong Rush vs. 200 HP / 0 Def Archaludon: 314-372 (84.6 - 100.2%) -- 43.8% chance to OHKO after Stealth Rock
Tusk coming in becomes almost a coin flip of whether or not it KOs Archaludon, and this becomes an 80% chance if it switches in twice or the opponent is using Spikes instead. Two layers of Spikes make it a guaranteed OHKO. You can definitely switch out if you don't like the situation you're in, but the matchup becomes riskier every time you do so. Archaludon wants to come in once and stay in as long as possible because entry hazards hobble its ability to keep eating hits. Tusk fears Draco Meteor, but AV Archaludon is the easiest thing to call out in the world. You need to be more aggressive.
I'm not trying to downplay Archaludon or say it's actually bad. But it sounds to me like your problem is that you're respecting it way too much. AV Electro Shot isn't even its best set. This is not banworthy at all.
