optimize(rosenbrock, [0.0,0.0], LevenbergMarquardt(), autodiff=:forward,upper = fill(0.75, length(x0)))

Results of Optimization Algorithm

Algorithm: LevenbergMarquardt
Minimizer: [0.75,0.75]
Sum of squares at Minimum: 351.625000
Iterations: 39
Convergence: true
|x - x'| < 1.0e-08: false
|f(x) - f(x')| / |f(x)| < 1.0e-08: true
|g(x)| < 1.0e-08: false
Function Calls: 40
Gradient Calls: 34
Multiplication Calls: 117

At the initial point, the value is 1.0 and clearly lower. Granted, it may be challenging to find the proper minimum. But 0.75,0.75 is very far off.
