No she didn't always have a form TK. Her powers were first "Hex powers", Then Chaos Magic(which is what you are talking about) , Then reality manipulation of course there is magic sprinkle as well. Anyways the point is none of things are well define and TK/telepathy is so when it came time to put her on big screen that is what they went it because someone thought it was simpler and more realistic. So yes it very much simplifying thing going hey this person can control things with her mind than hey this person use hex powers or chaos magic.
At some point thankful MCU stop caring about the Pseudo real nonsense and straight up embrace comic book wackiness Thor didn't have to be a space alien, Nobody try to explain logically how the infinity stones work,9 foot purple dude talking to tree and raccoon was fine, etc. So yes she very much has reality warping powers now they explain that when that Monica shot her pants in that episode.
