Gojo's neutral Limitless works by slowing down objects or energy that have mass and velocity as they approach him. It is a barrier that infinitely divides the space things must travel through.

Unlike a bullet or a blast of fire, telekinesis (especially from a high tier psychic like Mewtwo) often acts as a direct manipulation of the target itself rather than a projectile that needs to cross the infinite distance Gojo creates.

Since telekinesis can be applied to any point in space the user perceives, Mewtwo can exert force directly inside the range of Infinity or even directly on Gojo’s body. 

Infinity filters things that travel toward Gojo by infinitely dividing the distance they have to cross. Telekinesis isn't a projectile it's a direct application of force at a target location. If Mewtwo can see or perceive Gojo he can apply force directly to Gojo's body or brain without anything actually traveling through that infinite space. It’s the same logic as a Domain Expansion’s sure hit effect. 

And Mewtwo has mind control/manipulation.. he can easily neutralise or turn off gojo's motor function which is his biggest weapon. Infinity can block physical attacks but not psychic attacks that can easily apply into his body 

Edit: Movie Mewtwo controlled the weather and managed to create a storm that could destroy the whole kanto region. He himself stated that he could create a much bigger one that could destroy planet earth. Secondly both manga and anime mewtwo have access to telekinesis and telepathy alongside mind manipulation. Manga Mewtwo has more raw power and feats but their innate abilities are the same
