Tools > Autocorrect > ...is a pretty important menu. It not only lets you turn on/off autocorrect, but it also lets you access the Autocorrect Options dialog, which is pretty important because it lets you handle localization settings, replacements, capitalization settings, and also manage the collected dictionary of words for autocompletion, which can sometimes be quite borked up depending on the document, so it's important to able to access that. However, the Tabbed and Groupedbar toolbar modes do not provide you with any way to access this, even in the "Review" menubutton.
Good example why this kind of UI is a failure from the beginning, IMO. Makes no sense to squash hundreds of function into the primary UI. The least adverse effect is when we add the command to the Tools menu.

I'm not able to repro with the following: Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: e37dcb3ca36bb6c23b15757e6e556ad25832398c CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: threaded For Grouped mode, you simply need to enable the Menubar toggle under "Menu" on the far right-side of the bar. This will give you the Tools Menubar. For Tabbed mode, the "Autocorrect" menu is available under "Review"->"Review" (on the far right-side of the bar).
