We have a hosted application where clients do not get SQL Access. We have a new client that needs access to SSMS to write queries for reports. We are installing SSMS on a utility box for the client to log into and use. The clients accounts will be in the data_reader group. I want to force all queries to run READ UNCOMMITTED So not to cause blocking of the application with badly written queries

If by SSEM you mean SQL Server Management Studio (SSMS), there is an option you can set when logged in as this user to run as READ UNCOMMITTED by default:

But they could easily override that by unchecking the box, setting their own isolation level manually, or calling stored procedures that override. Features like Resource Governor can control a lot of things, but I don't think there's a way to hard-code isolation level for all queries a user submits...
