Correction, she was attacked by a guy with magic string. However, he was an inexperienced retard who left himself wide open and got dismembered by some kind of slicing wind spell. Both Frieren and the guy's own allies called him rash and stupid.
Frieren is powerful, but the whole point of the series is about how she is the long-lived mage from the party of heroes who killed the demon lord like 80 years ago. She is OP as fuck, but the draw of the series isn't the combat. It's in the interpersonal relationships, and how this thousand year old elf hag reconciles her feelings regarding the hero she spent a "mere" ten years with, long after his death.
I imagine you'd be more interested in a child-targeted shounen anime like Naruto, Dragon Ball or My Hero Academia. Something where the spectacle of the fight scenes is more emphasised than the story.
