Normal Leaflet Tile Layer (Grid Layer) has the opacity option.
https://leafletjs.com/reference-1.7.1.html#gridlayer-opacity
In your case you are using a special Tile Layer with Leaflet.TileLayer.Grayscale plugin.
However it properly extends the normal Tile Layer behaviour, and its code does not seem to make it incompatible with the opacity option. Therefore it should simply work:
var bkgLayer = L.tileLayer.grayscale('urlTemplate', { opacity: 0.75});

Turning the standard map to grayscale: I might be very late to this but for anyone else running into this question: I found a very easy solution if you're working with HTML and Javascript using OpenLayers and the standard OpenStreetMap-Tile-Layer in color. I took the solution from here: https://openlayers.org/en/latest/examples/semi-transparent-layer.html
I don't know much about web development but this solution worked for me. Upon creating the map, as done in main.js in the example from the link, a class name is defined ('bw')
className: 'bw',-
that can be used in index.html to manipulate the style o f it in the part:
<style> .bw { filter: grayscale(100%); } </style>
My application was altering a pre-built web-map from the qgis2web extension for QGIS. I was able to turn the tile layers from the background map to grayscale so the results would stand out more.

It is not quite clear about which specific process your are talking.
The tiles you see on http://openstreetmap.org are PNG, not SVG. The share menu allows to export the current view to SVG and some other formats. This resulting SVG is created server-side. Of course using less detail would speed up the SVG creation process But this process involves several other operations like querying the data base which won't benefit much from reduced details (ignoring the time to transfer the data between the database and the SVG creation process).
The PNG rendering will also depend somehow on the amount of detail but likewise there are a lot more operations necessary for rendering a single tile. I don't expect a large speedup by removing a few features.
Also note that there are several different renderers available and each will behave differently. And there is also the possibility of creating vector tiles which move some of the tile creation load from the server-side to the client-side. Here the amount of detail will slightly influence the server-side and significantly more the client-side, especially low-end systems.
Still I have no idea what these things have to do with mapping - the process of editing maps and adding/updating information.

- OpenStreetMap is built by a community of mappers that contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world. OpenStreetMap emphasizes local knowledge. Contributors use aerial imagery, GPS devices, and low-tech field maps to verify that OSM is accurate and up to date.

www.openstreetmap.org/about/api/How do I find an island in OpenStreetMap?
- For large and/or complex queries Overpass API is the way to go. You can use CloudMade's Geocoding API to search for an island in the OpenStreetMap data. The API will return the geometry of the result by default, and this sounds to me what you are looking for. For example, Arran off the coast of Scotland can be found by the following http request:
