I am looking for the examples of English words (if any) containing some variation of toll and sharing some etymological root with toll (so having a meaning like great or mad).

Quoting the Wiktionary on toll (boldface mine):
From Old High German tol, from Proto-Germanic *dulaz (“dazed, foolish, crazy, stupid”), cognate with English dull.
