I wikified it, should be possible now.

To block tlds:

Create a custom template:

mkdir -p /etc/e-smith/templates-custom/etc/rspamd/local.d/multimap.conf

Create /etc/e-smith/templates-custom/etc/rspamd/local.d/multimap.conf/90tld with following content:

#
# configure tld list
#

{
if ($rspamd{SpamCheckStatus} eq 'enabled') {

$OUT .= << 'EOF'
FROM_BLACKLIST_TLD {
    type = "from";
    map = [
    "${CONFDIR}/blacklist_from_tld.map",
    ];
    action = "reject";
    filter = "top";
    symbol = "FROM_BLACKLIST_TLD";
    regexp = true;
    description = "Refused list of FROM TLD";
}
EOF
}
}

Create /etc/rspamd/blacklist_from_tld.map with tlds to block like:

[.]com$
[.]at$
[.]de$

Apply changes:
