Long range cannot cure a surface raider's weakness

Did the Deutschland class's long range leave it vulnerable to the kind of situation Graf Spee faced?

That vulnerability applies to surface raiders generally: once found, a ship from the weaker navy faces the stronger navy's ability to concentrate against it.

Graf Spee's predicament illustrates a limitation of surface raiding by the weaker naval power. A raider will eventually be found. The stronger navy can then bring more force against it than the isolated ship can handle. Long range does not remove that underlying imbalance.
