Welcome to Atlassian Community!
There are two options to change Trello language.
You can change it directly on the board, by clicking on your Profile picture > Change language.
If the option above is not available, it means that you are using an Atlassian account, so the language can be changed on your profile in https://id.atlassian.com/manage-profile/account-preferences.
Please, give it a try and let us know how it goes.
