Yeah, but if he can't have bad luck.. at all... that would almost like having a good luck power. Not being affected by probability even just at a low level would be very strange, after all he deals in probabilities all the time when planning - and things do go wrong for him sometimes even just minor setbacks.. And if he can suffer bad luck at all (which I think he can) then Longshot can give it to him. I don't think Thanos's powers really protect him at that level.
Yeah, there are almost certainly some hax abilities in that tier that could do something useful. Ragman and Longshot have been mentioned but they are just for starters.
It would be the an entire tier as per the tierings here at KMC...
And while true there maybe some hax characters that potentially could bring down Thanos in these senario's, will they be able to with no prep against a Thanos with full access to his tech?
Also, Thanos has some of the best damage soak in comics for characters that are sub Odin level; he's resisted reality warp, he's withstood direct attacks from High Skyfathers and Cube Beings, he's got tremendous strength of will...
Inaddition (especially among the less tiers) he'd be wiping out characters like a white hot knife against butter...
Those he cant one shot he can bring down with mind rape or even turn certain characters against their comrads...
Now, I'm not saying that one of the lesser teirs cant beat him, but I'm going to have to hear a pretty convincing argument to be swayed in that direction...
Maybe he's not immune, but atleast accoring to Thanos in this link, outside influences have a minimal effect on his being...
So yeah, maybe Longshot can give him some bad luck, but enough to defeat him?
I can see enough to turn this from a stomp in Thanos's favor to him having to work for it, but defeating Thanos (especially with him being outside of Order and Chaos and outside influences having a minimal effect on his being) with nothing but luck seems to be a pretty tall order...

Thanos has resisted reality warping. He can attack you with psionics, he can vaporize you with energy blasts, he can transmute you into stone, he can control his entire molecular structure. I don't think Longshot is going to do much but get vaped.

He's not outside of Order and Chaos, though - they've specifically manipulated events and characters in order to bring heroes together, who defeated Thanos.
So if, as you say, he is immune to that, then he wouldn't have been defeated by such shenanigans. But he was - all thanks to the machinations of Order and Chaos, who manipulated probability to defeat him.
But take your point that he is NOT immune - then the degree to which he is immune depends.
You see, it doesn't matter to Longshot. All that matters is that he is OK. So what needs to happen to save him, will save him. Maybe Squirrel Girl (street tier?) just so happens to be stopping by. Nothing to do with Thanos, so why would he be affected?
But Squirrel Girl would be the ONE foe he definitely loses to. And so, she will appear.
