Wait for it to sleep climb on top its head. Whats it gonna do, flail at me with its puny arms? Stretch its leg up to swat at me standing on one foot? Drop and roll over crushing me om its ba- oooooh wait a min.

Hmm. Maybe I find a way to tie its feet first and stab it and run immediatly before it crushes me.

This is a fun idea

1: Keister some fentanyl in, poison the food with fentanyl, set food outside hut.

Depending on the dosage it will either die or be very weak for a while.

2: refuse knife, demand shovel. Dig giant holes to trap it. Possibly fill holes with sharp sticks so it's impaled or at least fucks up a foot or two. Bonus points for digging smaller holes all around the Hut then piss it off and watch it break it's legs.

3: depending on how intelligent it really is, you could possibly get it to do it's self great bodily harm. I caught an angry squirrel in a cage once. The squirrel just headbutted the cage over, and over and over. By the time I'd gotten to it it'd already busted it's head open pretty horribly, like it hurt to watch. Didn't stop it though, just kept headbutting that cage in a.. rage? Not even "normal" headbutts, these were full body jumps from one side of the cage to the other. It was trying to use it's head as a battering ram I guess. So maybe provoke the rex and run to your indestructible hut. Maybe it knocks itself senseless trying to get to you. Personally I wouldn't bet my life on that but eh, you do you.

4: just.. traps. Summon your inner Hunter. "What would kill this thing and how to I make that happen? Deep hole strategy again, collect some vines, scale a tree, hoist down with the vines above the hole and now you're bait.

Idk

As was pointed out I guess I'd have to dig the holes close(r) to the indestructible hut.

can the rex get into or manipulate the hut in any way?

I used to play a game called Tokyo Jungle, in it you can play various animals in a humanless version of Tokyo. The main goal of the game is to explore the city and survive as long as you can while eating plants or animals your animal likes. This game taught me that larger animals need more calories to survive, as my runs with the alligator would end the quickest, where with the smaller animals I could play for longer. I just fact checked myself and elephants eat about 330-375 pounds of food per day, and this makes sense, the larger the biology, the more cells they have, the more cells they have, the more energy they need to keep those cells alive.

Since a t-rex is much bigger than an elephant, I'd imagine they would need an insane amount of calories per day to survive. In a starvation contest, a human would win. All you would have to do is wait for the lethargy of starvation to set in, and then when it falls asleep try to puncture an artery or slice tendons to immobilize the dino. The idea is that it would be so starved that even if it woke up, it wouldn't have the coordination to immediately eat you, you may even have a comfortable window of time to seek shelter in the case that things go sideways. Or if you wanted to play it safe you could just wait for the t-rex to expire from starvation, but you'd most likely be feeling like shit by the end of that.
