Trouble moving live site to local

Hello!

Trying to move a very large install from live environment to local for some modifications.

I’ve run this script via cli to replace the occurrences of live site url (site.com) to my local one (site.dev).

So far, so good.

But when I try to access access site.dev I get Error establishing a database connection. And when trying to access site.dev/wp-admin I get One or more database tables are unavailable. The database may need to be repaired.

When attempting to repair the database this pops up

wp_posts: Table 'database.wp_posts' doesn't exist
wp_comments: Table 'database.wp_comments' doesn't exist
wp_links: Table 'database.wp_links' doesn't exist
wp_options: Table 'database.wp_options' doesn't exist
wp_postmeta: Table 'database.wp_postmeta' doesn't exist
wp_terms: Table 'database.wp_terms' doesn't exist
wp_term_taxonomy: Table 'database.wp_term_taxonomy' doesn't exist
wp_term_relationships: Table 'database.wp_term_relationships' doesn't exist
wp_commentmeta: Table 'database.wp_commentmeta' doesn't exist

These tables are not present in the live enviroment, so why should they be needed for my local install?

These are the MU specific stuff I have in my wp-config.php

define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'site.dev');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);

define('WP_ALLOW_REPAIR', true);

Really lost here, been struggling for a few days to get this far, and now I’m really stumped.
