The following hack has worked for me:

(use-package lsp-python-ms
  :init
  (setq lsp-python-ms-auto-install-server t)
  :hook
  ((python-mode . (lambda ()
                    (require 'lsp-python-ms)
                    (lsp-deferred)))
   ;; This hack is necessary to make additional flycheck checkers work in lsp-mode
   (flycheck-mode . (lambda ()
                      (flycheck-add-next-checker 'lsp 'python-flake8)
                      (flycheck-add-next-checker 'python-flake8 'python-mypy)
                      (message "Added flycheck checkers.")))))
