I'm creating a library part for a dual MOSFET driver IX442 which has 3 variants, IX4426, IX4427, IX4428. The difference between the variants is in whether the outputs are inverted from the inputs.
Is there a way to set the pin name for pin 7 (OUTA or #OUTA depending on the variant) such that I can create a single schematic part for all variants and use an attribute to set the pin name accordingly?
Each variant has to have a unique name. The first variant is usually named "" (empty string). You need to enter the names for the subsequent variants.

Just drag the output label over. It doesn't need to be touching the net at the label origin.
Note: To remove those little origin markers, use the set Option.ShowTextOrigins 0; command. Also note that this does not disconnect the label from the net, they are still associated (renaming the net will change the label). This simply moves the origin to not be on top of the net, so the two must be selected with the selection tool before being moved.

AFAIK, Eagle doesn't have this level of parametrization. [Neither do Altium, OrCAD.]
If you want to have distinct pin names** in distinct part numbers***, you'd have to make separate library parts. Copy and paste will do the bulk of the work.
** OUTA or #OUTA for pin 7
*** albeit they share the datasheet
P.S. You can tell eagle to draw a proper overbar by using ! sign
