The synopsis starts with an article, and it is a bit long (see “16.4.4
Synopses and Descriptions” in the manual for more details), I suggest

  GPG pinentry program for use with @code{trezor-agent}

The first sentence lacks a subject, and there should be two spaces after
a period.  I suggest

  This package provides a GPG pinentry program for use with
  @code{trezor-agent}, or for people with number-only PINs.  It displays
  a grid of unlabeled buttons and supports configurable keyboard
  settings.

The ‘license.txt’ file says BSD-2.

Could you send an updated patch?
