The LinkedIn dump is trivial to convert back into plain text. They're all SHA1 hashes and aren't salted. You can just download an SHA1 rainbow table[0] and instantly convert them to plain text.
The ones I linked to are brute force, every single SHA1 hash for all common ascii characters up to 8 digits long. You can also download smaller rainbow tables for common passwords, dictionaries, or similar.
Ultimately SHA1 is extremely fast to commute in 2016. So even if a rainbow table doesn't suit your needs, you can easily generate a new one which does, but likely you'll break a good chunk of passwords just using the "out of the box" 1-9 A-Za-z0-9 and specials rainbow tables.
