Yep, you can't delete a route that isn't there.
You could add a route for that network that points to an address which can't
route to the network, for example:
sudo route add -net 98.171.145.0/24 gw 127.0.0.1
or if you just need it for the current host you could add an iptables rule to
block traffic:
sudo iptables -I OUTPUT -d 98.171.145.0/24 -j DROP
if the current host is your router then the iptables rule would be:
sudo iptables -I FORWARD -d 98.171.145.0/24 -j DROP
Note: my iptables examples are horribly simplified things.
