If sudo needs a password, then it needs a tty, sure.
But sudo also complains, when it doesn't need a password, because NOPASSWD is in effect. Just had that situation a few days ago. And the reason for this is the requiretty setting in the sudoers file afaik.
ssh user@host sudo.. -> complaint,
ssh -t user@host sudo... -> success without asking for a password,
removing requiretty and ssh user@host sudo.. -> success

MTAIL(1) User Commands MTAIL(1)
NAME
mtail - tail variant designed for web developers monitoring logfiles
SYNOPSIS
mtail [options] <file>...
DESCRIPTION
MonkeyTail allows a user to tail multiple files on both local and remote hosts and clearly marks inactivity by putting 5 newlines in the
output whenever a pause in output over 3 seconds is detected.
MonkeyTail is implemented a fairly simple wrapper script around standard tail, ssh, and sudo.
OPTIONS
-q Quiet mode
--quiet
" "
-n Output the last N lines of each file before tailing (defaults to 0)
<file>...
Files to tail.
These can specified in the following ways:
@<groupname>
- expands the group (from .mtailrc) to a list of
files to tail
<filename>
- tails a local file.
+<filename> - attempts to sudo and tail a local file (will
prompt for pwd if required).
<remotehost>:<filename>
- attempts to invoke tail via ssh on a remote
host.
+<remotehost>:<filename> - attempts to invoke sudo tail via ssh on a
remote host (will prompt for pwd if required).
