You probably already have some idea of the way the US law school admissions process works. For a US student, LSAT score and undergraduate GPA are hugely important, although other factors are perhaps a little more important than people here would have you believe. For foreign students, the LSAT is the most important factor by a long way, followed at some distance by your LSAC-determined degree rating (superior, above average, average, below average).
Consultants can't help with those, so what can they help with? Well, the only other significant parts of the application are the application form, the personal statement, and the resume. The questions on the application form are generally so straightforward you shouldn't need any help. There is an accepted format for resumes - law schools even provide examples - so they can't really help with those either. That leaves the personal statement.
For someone like you, what they want in a personal statement is (presumably) something that explains why a German student in the UK wants / would benefit from a US law degree, while emphasizing positive aspects of your background and sounding like the sort of person they would like to admit (intelligent, interesting, intellectually and/or culturally diverse, with a clear mastery of written English, et cetera). So, the only question to answer is whether you need help to write something like that, and how much the help would be worth to you.
They probably also help you with other stuff - like whether law school is right for you, where you should apply, how to pay for it, what to expect, et cetera - but most of those questions you should be able to answer yourself with online research.
