I wrote the following toy program:

  (let ((confusing '(?а ?е ?о ?р ?с ?у ?х))
        (buf (get-buffer-create "*confusing*")))
    (while (not (eobp))
      (let* ((word (buffer-substring (line-beginning-position)
                                     (line-end-position)))
             (chars (append word nil)))
        (if (null (seq-difference chars confusing))
            (with-current-buffer buf
              (insert word ?\n))))
      (forward-line))))

and ran it on a list of 174800 words from a Russian dictionary.  The
result was 60 words that used only Latin-alike letters.  So, not too
many, but not just a few, either.

Of course, there are many more non-word combinations of the above
letters that might look like Latin words.

Also note that "confusability" sometimes depends on letter-case.  For
example, the lower-case "вор" doesn't look like a Latin word, but the
upper-case "ВОР" does.
