I use React, Vue, and Svelte extensively, and I don't think that there is any problem with integrating 3rd party JS libraries in any of these frameworks.
React, as the most bare-bones framework, might be simplest to integrate, and you can see that by the enormous size of its ecosystem.
Vue and Svelte will have problems with integrating various devtools, due to the fact they use custom syntax to mimic native web tech. In Vue, this problem is solved by framework popularity and the fact that the Vue team produced most of the key devtools, so Vue is, of course, supported.
Svelte, on the other hand, still works badly with Storybook and linters.
A good counterexample to your take will be that I was unable to use the JS version of Framer Motion with Svelte without huge caveats that made making any complex animation impossible. I wasn't able to do so with Vue, for roughly the same reasons, but Vue, as a big framework, got 1st party support.
