No, Kabz, it doesn't.

'Lift' is the resolved portion of the total force and acts at 90 deg to the flight path. It's not possible to resolve a parallel component from a vector that acts at 90 degrees to the plane in question.

The Total Force is what is inclined. The rearwards component gets resolved into a force labelled as 'Drag' ie induced drag that acts parallel to the flight path.

Yes, Lift is inclined 'backwards' in relation to the (earth referenced) horizontal plane however the components of forces as we label them are defined around the (aircraft referenced) flight path.
