You don't need to use LS. If ICMP requests are not allowed for this host, you could change your "host alive" command to use something else, e.g. using check_tcp against a port that is open, etc.
Here's our documentation on changing the host alive check command:

Yes, you can run the Nagios Log Server Wizard, and use the "Text Queries" section
The example below will give a count for the host "192.168.5.153" and warn if over 50, critical if over 100 in the last 15 minutes
