This can happen with all sorts of accounts for all sorts of games no matter if theyre high quality or not. Just buy from a reputable seller that can also provide support if theres something wrong with the account.
Is there any risks to buying high quality LoL account especially with a lot of champs and 100+ skins or something?
Is there any guarantee I will own it to all myself? People could easily take their account back through Riot support, right?

I've had a account from a rep person (all champs, 600+ skins), and the original owner took the account back after 1.5 years. The seller couldnt give me a replacement cause he had nothing like that in stock. Offered to give me 3 lvl 30s with 50000 BE each.
Word of advice, dont do it. The only place i really trust are websites that actually take precautions. (EX: Before a person can sell an account to that website, they must provide ID, CC Pics, ID next to face etc)
Don't do it. I bought a $200 acc and Riot locked it randomly two years later because my IP didn't match the sign-up IP. The original owner didn't even recover it, nobody has used the account since then (this happened last year).
Just make your own account and build it up.
