LR classic without membership

If you are not going to want Lightroom Classic or Photoshop at all, you can subscribe to only Lightroom if you want. The same is not true the other way: you cannot subscribe to only Lightroom Classic. When equipped with the same amount of cloud storage, the Lightroom-only plan costs you less per month than the combined plan does.

If you do use Photosop you can subscribe to only that also, but that becomes more expensive than subscribing to the package plan that includes all three applications.

If you have previously had a plan that included Lightroom Classic and then you cease subscription (or, switch to a plan that does not include Lightroom Classic) then you can still use this software - but only in a reduced mode.

In that reduced mode you can still see all your previously edited photos, manage and export images from your image library (the Catalog) but the main editing tools -  the whole Develop module - is unavailable to you.
