os_newsyslog_files_owner_group_configure and os_newsyslog_files_permissions_configure get the list of files via:

/usr/bin/grep -v '^#' /etc/newsyslog.conf | /usr/bin/awk '{ print $1 }')

Files inside /etc/newsyslog.d are ignored.

Also, ownership and mode can be configured directly within newsyslog.conf files via the optional second and third columns, though it may not be a good idea since e.g. /etc/newsyslog.d/com.apple.xscertd.conf explicitly sets ownership to _ces:admin.

Suggestions

zsh globbing is used to handle log rotation, but I don't have any log-rotated files on my machine to verify.

Checking for ownership:

logfiles=$(/usr/bin/awk '!/^#/ { print $1 }' /etc/newsyslog.{conf,d/*})
own_err=("${(fu)^logfiles}"*(N^u[root],^g[wheel]))
echo "${#own_err}"

Fixing ownership:

logfiles=$(/usr/bin/awk '!/^#/ { print $1 }' /etc/newsyslog.{conf,d/*})
/usr/sbin/chown root:wheel "${(fu)^logfiles}"*(N^u[root],^g[wheel])

Checking for permissions:

logfiles=$(/usr/bin/awk '!/^#/ { print $1 }' /etc/newsyslog.{conf,d/*})
perm_err=("${(fu)^logfiles}"*(N^f0640))
echo "${#perm_err}"

Fixing permissions:

logfiles=$(/usr/bin/awk '!/^#/ { print $1 }' /etc/newsyslog.{conf,d/*})
/bin/chmod 640 "${(fu)^logfiles}"*(N^f0640)

Checking ownership misconfiguration:

/usr/bin/awk -v err=0 '
    !/^#/ {
        if ($2 ~ /^[[:digit:]]+$/ || $2 != "root:wheel") {
            ++err
        }
    }
    END { print err }
' /etc/newsyslog.{conf,d/*}

Fixing ownership misconfiguration:

/usr/bin/sed -Ei 's,^([^#][^[:space:]]+[[:space:]]+)([^[:space:]]+:[^[:space:]]+)?,\1root:wheel ,' /etc/newsyslog.{conf,d/*}

Checking permissions misconfiguration:

/usr/bin/awk -v err=0 '
    !/^#/ {
        i = $2 ~ /^[[:digit:]]+$/ ? 2 : 3
        if ($i != "640") { ++err }
    }
    END { print err }
' /etc/newsyslog.{conf,d/*}

Fixing permissions misconfiguration:

/usr/bin/sed -Ei 's,^([^#][^[:space:]]+[[:space:]]+([^[:space:]]+:[^[:space:]]+)?[[:space:]]+)[[:digit:]]+,\1640,' /etc/newsyslog.{conf,d/*}

Changes can be inspected by running diff in a loop:

for f in /etc/newsyslog.{conf,d/*}; do
    diff --color=always --unified "$f" <(/usr/bin/sed -E 'SED COMMAND GOES HERE' "$f")
done
