You do not desperately need it. I don't see why this is a problem and why you prefer server crashes over a module require, but you can remove the two lines resposible for the require.
PHP Code:
if( !is_user_alive( BotID ) )
ExecuteHamB( Ham_CS_RoundRespawn, BotID );
Search these two lines, remove them and it will still work. In some situations, however, this will cause some minor issues. Maybe a dllfunc spawn is also possible because they are only fake clients.
