Google is gone. No app store, no YouTube.

I let someone touch my phone, now everything is gone except for Google Search.

Make and model phone? Service provider?

Who touched your phone?

What specific things (I.e., "everything") are gone?

Maybe they deleted the icons and/or blocked your access.

More information needed.

If youre using samsung, If i remember you can hide apps.
Usually i could do this by tapping on all apps , in top right corner 3 dots and there should be a menu for hiding apps?
