Thereʼs nothing stopping you from doing that locally:

(with-temp-buffer
  (activate-input-method "TeX") ;; the input method has to be triggered for `quail-package-alist' to be non-nil
  (let ((quail-current-package (assoc "TeX" quail-package-alist)))
    (quail-define-rules ((append . t))
                        ("\\lll" ?⋘))))

(I donʼt use the TeX input method, so I canʼt judge if doing that by
default makes sense, although adding it as an alternative seems
relatively harmless.)
