Untested, but you had a few variable issues. Try this one:
<?php

function featured_post(){
global $wpdb;
$featured_blogs = array(1,2); //Update this array with the ID's of featured blogs
srand(time()); //Do not change this
$random = (rand() % count($featured_blogs)); //Update this with the number of entries in the array above
$thispost = $wpdb->get_results("SELECT id FROM " . $wpdb->posts . " WHERE post_status = 'publish' AND post_type = 'post' ORDER BY id DESC LIMIT 0,1");
$featured_post = get_blog_post($featured_blogs[$random], $thispost);
$post_author_id = $featured_post['post_author'];
$post_author = $wpdb->get_results("SELECT display_name FROM wp_users WHERE id = $post_author_id");
$permalink = get_blog_permalink($featured_blogs[$random], $thispost);

$blog_table = 'wp_' . $featured_blogs[$random] . '_options';
$blog_name = $wpdb->get_results("SELECT option_value FROM $blog_table WHERE option_name = 'blogname'");
$content = explode(' ',$featured_post['post_content']);
for($i=0; $i<200; $i++){
$summary[$i] = $content[$i];
}
$summary = implode(' ', $summary);
//Lets Output the Post ?>
<div class="entry entry-1">

A lot of what you are doing isn't very optimal. For instance, to get the first 200 characters of a string, you only need to do:
$summary = substr($content, 0, 200);
If you want the first 200 words (as you have above), you can do it as:
$summary = explode(" ", $content, 200);
$summary = implode(" ", $summary);
